Hmm, I'm not sold...
Firstly, I admit, I was like WOW!! Fook me, etc.
Then I was like, hang on, I feel sick just watching this video so it'd be no good for me - I felt really sick when I setup Skyrim on 3 x 24" monitors over Xmas, so I know it's just me, but all the same.
Lastly, as we got towards the end, I twigged something. What exactly is the point?? In the end, it all boils down to extending the picture beyond the screen. Just buy a projector and use your whole wall - that's essentially how it ended up at the end.
OK, so there were some effects in there that were way more than just a bigger than TV experience, but for the most part that was what I felt it was
Will keep an eye on it if I can get over my motion sickness though.
