While some of the things they've mentioned sound cool, its not enough yet to convince me to run out and buy one. I've already got the software and hardware to record my gameplay, but that is something that won't cost us another couple hundred to do if we wanted to. The games they showed, not my kind of games. I'm a Shooter gamer, and none of those really caught my attention.
I'm just curious to see how Microsofts next Xbox can top the current Xbox 360.
