As far as emulation on Next genreation consoles, ITS NOT HAPPENING for 6 years from now. These consoles are new, no documentation is available for them at the moment, and there isn't even Homebrew development on the Wii, XBOX360 or PS3 yet.
Should you expect PJ64 on the Wii soon? Hell no, also I see some ignorance on a few people here.
I am pretty sure Nintendo will crack down on previous games they are selling as a service on their brand new console being hacked, hi-jacked, and emulated for free. Why? Because it is lost revenue, emulation isn't about just playing games. Although that is what emulation has evolved to.
Bottom line, don't ask for emulators on next generation consoles for a few years. Not only for the complexhardware and software these consoles are drivin by, but its just too early in its life to just happen in 1 week.
