Ain't those exclusivity things a little bit tricky ? My guess is that Sega would mean " 3 games Sonic is exclusive to Nintendo " instead of " 3 Sonic games exclusive to Nintendo "

If that's the case, those 3 games would be :

Sonic Lost Worlds
Sonic & Mario at the olympic games
Sonic in Super Smash

With that said, Sega may already be making a game for X1 and PS4.

 

No they definitely said there were three Wii U titles, Sonic being in SB doesn't count. So there's one more game, we just have no idea what it'll be.
