The Xbox One is also switching its CPU. It's using the same one as the PS4. The X360 used something entirely different from the XBOX 1.
Well that makes a lot more sense. I was thinking of switching to the new Xbox (was a PS3 owner) as I was hoping it would have backwards compatibility. That's a huge library of games I missed out on. Too bad... Now I'm not sure which I will get. I guess the best thing will be to wait for a year or so and see which system has the games I want to play. It'll probably end up being the PS4, but at least I'll be able to get it at a cheaper price and with a better library.
