I know I'm getting COD: Ghosts for sure, and probably Battlefield 4.
I'm on the fence about Killer Instinct. I remember playing KI for SNES with my brother growing up, so I kind of have a soft spot for that game, but I'm not a big fighting game fan. I might consider picking it up and learning the craft just for it. I don't know...
For everything else, I'll try out Dead Rising 3, Ryse, The Fighter Within (to try out Kinect), maybe Assassin's Creed IV (not a big AC fan), and maybe Crimson Dragon (which could be a sleeper hit for Xbox One.)
I was the same way with the Xbox 360 at launch. I bought Perfect Dark Zero first because of it being Perfect Dark (regret that to this day), and then Call of Duty 2 (still awesome to this day!) and that was it for a while after launch.
With all that being said, there's no question that the launch titles coming up are shaping up to be a lot better than last gen, more diversed too. It sucks about Watch Dogs because that was on almost everybody's wish list, but the delay will make for a better game... hopefully.
