I don't care about Sonic's design, I'm more concerned with Sonic during that year. We don't know what that Sonic 25th Anniversary game is gonna be like (though personally that "going back to roots" statement doesn't give me confidence), and all we have to fall back on are yet another mediocre Sonic & Mario game and another Sonic Boom game that we know so little about.
Frankly, stuff like is why I'm more interested in the Puyo Puyo 25th Anniversary next year.
