User blog comment:Tails1/Is Sonic's Future with Nintendo trouble??/@comment-4533965-20130517210948/@comment-1889468-20130518014148

It's not exactly what you think. Sega and Nintendo aren't collaborating, Sega is completely making the games by themselves  (save the olympic games)  so its not even a partnership, as much as it is a promise to make the 3 games only for Nintendo platforms.
