ARM out in favour of x86, sources say. http://www.bit-tech.net/news/hardware/2014/12/01/google-glass-intel/1
On what grounds? Fun fact: in the UK, it is perfectly legal to take photos or video of anything you want in a public place as there is 'no reasonable expectation of privacy.' Yes, this includes taking photos of things like police officers; despite what some might insist, there's nothing they can do to stop you (although they can antagonise you then arrest you for 'breach of the peace,' which is often police-speak for 'looking at me funny.' You can, however, be done under the Counter-Terrorism Act 2008 for 'publishing or communicating' such a photo, unless it's of a plastic (PCSO) 'cos they ain't real coppers, innit.) 'Course, you don't have to take my word for it: here's the Metropolitan Police guidance on the matter. Other countries have other laws (France, in particular, has some weird icky-sticky laws about photography in public) but over 'ere it's perfectly A-OK. Now, as has happened in the US, it's possible to be banned from taking photos or videos in a private place for any reason whatsoever - hence people being banned from wearing Google Glass into a cinema where they could record the film. S'no different to how you'd be treated if you tried to take a video camera into the cinema (likewise, while you're allowed to take your 'phone in you'll be ejected if you're seen to be using it to film the screen.) Shopping centres, too, often either ban photography outright or require permission to be sought first. TL;DR: Don't be daft, rollo, nobody's going to ban Google Glass (or any other recording device) in public in the UK.
