The whole "worldwide exclusive partnership" thing Nintendo seems to be playing up with this title implies that Sonic: Lost World will probably stay on Wii U. I mean, it's not the first time we've had a Nintendo-exclusive Sonic title, but they seem to be emphasizing that it's a collaboration between the two companies.
Let's hope it continues the trend of recent Sonic games being... you know, good. Ah, who am I kidding? I'll buy it anyway.
