It is NOT going to be Android-based. So many vulnerabilities that would be present, it's not even funny. If Nintendo doesn't want their console to get hacked a week after it comes out, they just can't have it be Android-based.
I've never even heard of this site, so I wouldn't get my hopes up high. And if it is a Wii U and 3DS game, it can't be Retro's game (unless Nintendo Software Technology does the 3DS port, not unlike Metroid Prime Hunters and Metroid Prime 3).
I think that it would be wise for Nintendo to have at least 1 USB 3.0 port. Given that the console will most likely be out from 2012 to 2017, they need to have the technology available to keep up, and in 2017 a lot more devices will be 3.0 than 2.0. It's kind of like Wi-Fi with the Wii-in 2006, most Wi-Fi was in public places and not in homes.
