What IS staying for Wii is just the general online stuff (Internet Channel, Hulu, Netflix, Youtube, etc.), the Wii Shop Channel, and any games that have DLC (Samba De Amigo, Rock Band, Guitar Hero, one of the Final Fantasy games).
It's a shame to see this happening, but on the other hand, it doesn't surprise me. I went on 6 Wii online games and there was no one playing. Rarely will you see anyone online other than for RB, COD, Mario Kart Wii, and Brawl. It would be nice to do a nice reunion to get everyone together to play out all our online games (it sucks I can't for Smash Up). I want to record any online moments we do, and probably even do some commentary.
