I know a little bit about Nadir from huinting around a while ago. I don't believe this is a scam. He seems to be guy into gaming and a budding entrepreneur .
It's actually true that he started looking at Bay trail and cherry trail devices for gaming 2 years ago. You can see that on russian forums.

He is a 3d CG specialist who supposedly started his own business 3-media.ru when he was 20 . 3-media.ru is down now though. He also won a grant when he was 20 to study overseas ->
http://moidagestan.ru/news/society/9515 - He is the young guy in the middle with the glasses hanging from his shirt. His now 25. He specialises in doing the 3D CG work in TV ads etc. He has a demo real of this which I've posted previously. This one -> vimeo.com/79775846
So what I believe is happening here, is that here is a guy who's into gaming, he is also good with 3D CG work and has connections with doing ads. He has an idea to develop a portable gaming device , but he doesn't have the skill set to do it. So he he seeks investment. He is forced to go onto KS (whether you believe the investor exists or not). So what does he do. He wants to put the best marketing package together for the KS PGS video. So what does a 3D CG specialist who has worked on ads and has connections with people that make ads do. Yes, of course his going to go down that route ie do the 3D CG work for the PGS and use his connections to hire actors and put together a flashy ad. Which gives the false impression of a full working team
Thats when the wheels start falling off, as although they have been honest to some degree admitting things. It's only after they have been discovered usually. Sadly though, they seem to have held onto the ad being people still in their team rather than admitting it was an ad. Then their is the dubious connections (someones father - lets leave it at that)
So I'd say his an entrepreneurial dreamer who does want to create this, but went slightly the wrong way by doing an ad, and not being totally upfront. Sounds familiar right?
