From what I've heard about the next console generation, I didn't think anyone with a mind would consider getting the new systems. The Wii-U seems to sound stupid, and when Nintendo Power said they'd have a "pro" controller which resembled a 360 controller, and I knew what I wasn't gunna buy.
The PS4 or whatever apparently is going to eat your games, essentially trying to kill EB games. I'll stick with my CPU thanks, at least I can bring my steam account over to my friends house a hell of a lot easier than a PS4.
I've heard nothing about Microsoft, but I don't use my 360, Wii, or PS3 very much anymore, so why should I bother?
As those above have said, It's mostly because no ones been able to buy any yet, so nothing is happening. Nintendo fan boys will buy it, and I'll probably buy it the moment It's cheap as shit like the Wii is now. Nintendo isn't going to be harmed much, they'll spring back, they always do.
