I like a lot of what The Buzzsaw has to say, I've said this elsewhere, but all the other two consoles are just trying to be computers. I'd rather play games on my computer and save the money. If I want I'll just hook up the TV and use it as a monitor. If the controls aren't fun, then we just need controllers that hook up to the computer and we're fine.
HD Nintendo? Good enough, I don't care if it isn't better than eve what we have now with the other systems, I've seen what it can do with The Legend of Zelda, that is PLENTY of graphical power for me, it's beautiful.
Some people say consoles we end up dying and PC gaming will rise. The only thing that reminds me that it isn't entirely true is Nintendo.
