Good analysis. Glad to see people have common sense on this forum...
I am in the same boat as you (only late 20s :) ) and Kinect does nothing when it comes to gaming for me so far from what we've seen. However, as a media control device...oh man, that thing is awesome.
You see, I'm a lazy bum when it comes to video games. I sometimes don't play the game I want because I'm to lazy to change the disc :)
I will gladly pay 100 bucks to have this motion control addon for my movies, and xbox live browsing. And if a bunch of cool games come along as well...I won't be too upset.
Otherwise there is still tonnes of core software that X360 owner will get to play only on that console this year. Alan Wake DLC, Crackdown 2, Summer of arcade (which looks freekin amazing), Halo Reach, Fable 3... on top of the shared 3rd party games.
Now for 2011, they need to show us more love than Gears 3, but I'm sure they are working on that. I mean, they better...
