It's the Shield Tablet minus accessories. http://www.bit-tech.net/news/gaming/2015/11/18/nvidia-shield-tablet-k1/1
For what I can see on Nvidia's website, all accessories are now optional, but still compatible with the tablet.
Except that there's no slot for the stylus, and no software support for activating things when the stylus is removed from the slot that doesn't exist any more. Other than that, yes: as the article says, the tablet is otherwise unchanged from the original release.
Last line: "The Shield Tablet 2 is on-sale" -> "The Shield Tablet K1 is on-sale" Wishful thinking, eh?
