Voted No.
I can't afford a new console for one thing. I just replaced my XBox 360 after the last one overheated to death.
For another, what could it possibly offer to make gaming better than it is right now? The 360, at least, offered HD, it plays DVDs and it was my first exposure to Xbox Live (with the marketplace and the arcade and the anonymous multiplayer). It even introduced Kinect -- which, while not for me necessarily, was at least new and interesting. I can't see how a new console would follow that act and top it to such an extent that it convinces me to shell out all over again.
Okay, that might have sounded a little short-sighted. There's plenty of neat stuff a new console -could- do that the current Xbox 360 doesn't or can't do. But I'm an old-fashioned console gamer. I want to buy a cartridge or a disc or whatever, put it in the machine (preferably without having to blow on it first) and play the game I paid for. And frankly, the current 360 does that perfectly well. It also adds plenty of neat stuff that I never use. I don't want a new console full of even more neat stuff I already know I'll never use.
Also, there are no game IPs currently out that I'd slavishly follow to the next generation. I followed Halo 3 onto the 360 because of how much I loved Halo and Halo 2, but I don't see myself doing that for Halo 5 or 6 or for whatever that new persistent shooter MMO thing is that Bungie's developing. Assassin's Creed, Mass Effect, Fable... all their #3s left such a bad taste in my mouth that I wouldn't follow them over. (I don't even know if I'll buy Assassin's Creed 4 on the 360.)
So... there.
