According to these specs the Rev would be a Mac Mini with a faster CPU and a slower GPU. That makes no sense in my opinion, especialy for a device that will be visualy intensive.
I also think that Nintendo would go with a larger amount of RAM, maybe 256~512MB.
480p only, come on, I believe even Nintendo would not be that silly. I'm pretty sure they will go with the standards set by the ATSC and go all the way up to 720p and 1080i, and maybe 1080p, which I think is catching on in Japan.
Like everyone else I want to know were the hell the HDD came from when Nintendo themselves said that it will have 512 MB falsh memory.
I think this is someones idea of a joke.
