Not to forget no ones even seen an X-box one in action.
http://www.techpowerup.com/185721/microsoft-pulls-a-fast-one-with-e3-xbox-one-demos.htmlI know a lot of people will scream 'emulation' and that it would be the exact same as what the Xbox One actually can do, however the fact of the matter is that all E3 Xbox One demos were not using an Xbox. Does that mean that their dev kits aren't working? Is there flaws that they don't want to exhibit? or maybe they aren't as pretty as they are trying to sell, i wouldn't go so far as to say that some of the games displayed were touched up with some A:CM movie magic, but its possible.
