NINTENDO DOES NOT NEED TO UPDATE THE GRAPHICS BECAUSE GRAPHICS ARE GOOD ENOUGH NOW!
I hate people saying the graphics are outdated/weak/etc., they're fine, they do massive 3D worlds in good detail don't they?
HDTV will need widespread adoption before it becomes a must-have feature on a console because a) Graphics are good enough now and b) They're not free on street corners - they cost twice the amount an HD console could cost and it will take 5+ years for most gamers to have one.
Blu-ray is even worse off, as you need to sell even more expensive players for high-capacity optical media and they're not much better than DVDs but cost far, far more and there's not many films out on it versus DVD, plus the market is split between HD-DVD and Blu-ray so real enthusiasts must buy both!
I do think virtual reality (Don't. Use. Brandnames. For. Generic. Technology.) is the next big thing in gaming though.
Ubuntu. Linux for human beings.
