I still want to see a better quality video of the Japanese garden demo. Web video blurs the image and I can't see fine details. If anyone sees an uncompressed capture of the demo, please post it here. Watching it again, I don't see anything technically new, and it really does look like 2008-era GPUs being pushed to the limit. I'm guessing it's customized somewhat more than a stock 4830. I ran my 4850 at 1080p on most games, but performance wasn't quite up there with the overhead of an OS. It should be enough, but I still wish they had gone with a current-generation GPU. Watch AMD's HD 5XXX and 6XXX demos (especially order-independent transparency), there's a lot of neat effects and techniques that I would have liked to see in a console GPU.

I don't think storage matters unless Nintendo plans on doing digital distribution for full Wii games. For WiiWare and Virtual Console stuff, 8gb is actually pretty good.
