Why does everyone only mention Nintendo games, Matt disn't say it was a Nintendo franchise.
Earthbound is not going to be huge news, since it's a small franchise outside Japan. Kid Icarus is a single game, not a franchise as such.
I think more in the direction of Mega Man and Castlevania. Enormous franchises that will stop the internet the moment they will come to Wii exclusively.
Donkey Kong platformer is a good guess as well.
