    Sharp have announced 4K (3840x2160) 5.5" screens for next year's crop of high-end smartphones. Maybe...

    LCD rather than OLED though.
    While LCDs can also be run as low-persistance displays, they have a latency penalty (you need to wait for the slowest pixel transition to finish before you pulse the backlight). There are also visual issues when driven at high refresh rates; you don't notice them much on stationary 144Hz TN panels, but when you are moving your head and your eyes are tracking along the display the partial transitions and overshooting (from the harsh overdrive needed for fast switching) become more obvious as contrast trails behind objects or the environment during head motion. VOR strikes again. Similar to the 'black smear' issue with the Note 3's OLED panel, but worse (lasting more than 1 refresh) and occurring behind every transition.

    makes no sense... why smartphones, do you want to charge your phone now 3 times a day? why do they not put tech into better batteries first.

    Technology development does not work that way. Research into increasing panel patterning density has no effect on research into battery chemistry.

    Facebook have confirmed in financial reports what was already known. OR Will not see launch in 2015, Not a huge shock in truth.

    No they haven't.

    Go back and read what they actually said.

    To summarise: it's the financial legalese version of "we have nothing to announce at this time".

    In earnings calls like these, saying "we expect to ship x million units" is a formal statement of intent, and failing to do so can result in legal action against the company. For a device that is still in development, or even just entering active mass production, this would be a ludicrous thing to do.

    Well Steam & HTCs VR will be beating Facebook to the punch then it seems.

    Who knows? So far they have only announced that it will be available this Autumn. And even with HTC manufacturing the headset, it's still subject to Valve Time for the controllers and Lighthouse.

    Plus, there needs to be enough time for developers to actually develop anything. Swapping the Vive for the Rift in terms of the HMD is almost trivial (as demonstrated by people parallel-developing for the Rift and Morpheus), but that's just basic compatibility. Developing to use the controllers will need large changes to interface design, and developing for small-volume-walkaround will mean nearly a whole new game (if it;s to be done properly) due to both the new abilities, and new constraints.

    Even a confirmed (which it's not) 0-impact to Facebook's earning call this year only means that Facebook do not expect to make any profit from Oculus this year. Which could easily mean selling CV1 at-cost, which has been the stated objective of Oculus for quite some time.

    Think people are forgetting valve and htc are strictly going after gamers. Facebook is not just going for gamers with its device. 2 very different target markets.

    Valve will guarantee there's a few titles ready for the launch that's for sure.

    Can't see Facebook loosing money on rift. Sold at cost will not be there cost to manufacture it will be cost + advertisement at a minimum.

    I can't see Oculus targeting anything other than the gaming segment for mass-market for at least CV1. This is also what thay have repeatedly stated publicly, before and after acquisiation by Facebook. There simply isn't anyone else with sufficiently powerful PCs to run VR at the moment. Sony can get Morpheus running by having a fixed platform (a big advantage for latency-focused optimisation),

    Rollo, you seem wildly misinformed. I don't know how many times they need to say its all about the games for people to believe it.

    Anyone know if there's any rules about reselling these, I'm sure there was something but I can't find it?

    There's nothing to stop someone reselling a DK1/DK2, but Oculus have explicitly stated they will not provide any support for devkits not purchased directly from them.

    Till one of them gets a launch date of some description it's still all talk with little to show.

    Valve / htc
    Oculus

    Both can offer what people want. Valves seems more complete of the two with them having a working controller for there target sector. Whatever is first to market will get a lot of the hype that has refused to buy Dev kits. ( like myself, tested dk2 but never owned it.)

    There's also how big a issue not having a pre configured controller will be for others to deal with. That's why people assume Valves will be better for gamers.

    A lot of it will come down to price sub £300 will likely be the target for all VR products. Any more and they will be pricing themselves against 4k screens.

    That will be a fun battleground VR vs 4k can not see both succeeding.

    xbox one/ps4 controller. x360 controller if you don't want to spend out. All three are far superior to valve's controller in many people's eyes.

    The big problem with shipping a bundled controller is future lock-in: If a position tracking controller with a touch thumb pad and a few side buttons is what is expected and developed for, then that's what everyone will end up shipping for the foreseeable future. Whether it is the best input solution available or not. e.g. the NES 'nailed' console gamepad inputs, and the digital D-pad stuck around as the primary directional input for consoles for a decade the analog stick re-emerged. Or Xinput, which makes it easy to implement controller support but said support is inferior to DirectInput or USB HID devices in controller flexibility.
    It's a big gamble to effectively standardise VR input so early.

    Nonsense. Pitching VR against 4K flat panels makes about as much sense as pitching speakers against headphones.
    Unless a new display panel manufacturing technique arrives that favours medium-scale panels over larger panels (it's not the same situation as with LCOS and DLP), then flat panel monitors will continue to outpace VR in pixels-per-degree for the forseeable future. We're a long, LONG way away from hitting even he regular '20/20' contrast-discrimination acuity limit of the eye, let alone vernier acuity. It will be several generations until a HMD-based virtual desktop could approach the effective resolution of current desktop panels, and desktop panels will be becoming denser all the time.
