This lends credence to my theory that Nintendo is stealing ideas from its fans; and no, I'm not joking. A year or two ago, I sent a letter to Nintendo about an idea for a game I had that involved Wario using different costumes to get different powers, for the DS. And lo and behold, there is now Wario: Master of Disguise, which uses a very similar idea (which, incidentally, I ripped off of Little Nemo, which no one else has played).
