According to Stephen Totilo at Kotaku, Rocksteady chief Sefton Hill has denied the nostagically delicious rumor that the Batman: Arkham City developer was
not making any sort of Teenage Mutant Ninja Turtles game.
The evidence is really not that compelling, considering that every developer denies every rumor. If Rocksteady really isn't working on a TMNT game, they better be making a Spawn game. Or a Batman game... maybe.
