Mario & Sonic will always stay as a Nintendo and Sega partnership thing, so I was honestly hoping that the 4th game wasn't a part of the 3 Sonic games.

Really, though. Nintendo and Sega should extend their partnership (or maybe even have Sega become a full subsidiary of Nintendo, but then of course, rage mode from other players so shoot me).
