I haven't thought about any console as a visual powerhouse since PC gaming took me over in like 2003. I get the whole HD thing and playing on your TV, but with any decent video card you can do the same. Hell, you could use a 360 joypad if you wanted to, but why someone would want to give up mouse and keyboard control is beyond me.
If Nintendo releases a console in the future that just pushes graphics, I'll have to pass on it. Consoles are becoming more and more irrelevant when they just try to copy PCs.
