If you've been paying attention this past week, you'll know that Tetsuya Nomura isn't just making new games, he's making his old ones, too (to raucous hype).
EDIT: I'll add Daisuke Ishiwatari and Fumito Ueda. It's hard to think of someone in the West, though. A lot of them got run out. Amy Hennig's an infamous case.
