Yes, but it's running background processes of the hardware like verification and such and I don't think it's actually accessible for developers. If this'd be a launcher or a VM of sorts then it would not be enough juice in my opinion, it'd have to be a full-blown bootloader, and that's a lot of reverse engineering right there. I don't think it'd work that well, it'd be easier to focus on the more powerful of the two beasts in the Wii U and work with that. I guess we'll see - it's not like we need Android, any Linux/UNIX will do.
Yeah, I know, we don't need Android, only I was saying, you are right, that CPU it wouldn't be accessible for developers, but if we can exploit the Wii U and have all the system control... well I'm only thinking, anyway, it will took a lot of work for nothing, Android in Wii U would be useless for me, as I say, I have my phone for it xD.
