Until they release multiple bad games in a short time, they are not the new Rare.
Retro has released 2 original games in 7 years. Mario Kart 7 and DK Tropic Freeze.... I can't see how anybody has faith in Rare at this point in time. Something is clearly wrong with the studio. DK wasn't even that great of a game. And the Mario Kart formula is well established. So really, Rare hasn't done much of anything impressive since the Wii via Metroid Prime 3.
