I think Tanaka worked more for the sake of getting the game out as soon as possible and then improve it while we're paying, and Yoshi's team is more for waiting and releasing a quality patch.
waiting to make sure content is as good as possible is exactly what blizzard does and they have yet to release a game of less than excellent quality. (i'm not being biased, i don't like WoW but it is still an excellent game)
people just need to learn to be patient. when the game goes pay to play is the day i'm reserving judgement for this game.
