Insomniac is not doing anything for MS exclusive. I don't know where this crap gets started. And of course MS will have games - eight of which were on the screen briefly shown. Of those, the Rare game shown looks like garbage, Halo, Forza, Ryse, were all there.
There will be a butload of Kinect including a Fitness, Sports, and Dance game that are all fully Kinect. Most everything else is Kinect-enhanced in some form or fashion. Gamers who don't like Kinect aren't going to like this show, except for the third party announcements.
There will also be CoD in some form, as well as Titan. No indie games whatsoever, as MS has treated them like dirt and they all have moved to Nintendo and Sony. If you like Indie games, this isn't the platform for you. The Xbone will sell well in the USA (because Americans don't care about anti-consumer policies), and pretty much nowhere else initially. Eventually, after they show the next Halo game, that might change.
Definitely not the system for me. I hate anti-consumer policies, and MS has shown their true hand. They couldn't win me even if they bought TLG from Sony as an exclusive. I don't support companies who do those things. But many do - look at Live
