To anyone waiting for a lower price: I'm a cheapass, too, and I'm not judging. But I will say that the game is pretty amazing. Incredibly solid gameplay, amazing visuals, amazinger audio. Plus lots of content, plenty of replay value, and no shortage of tough-as-nails challenges for the die-hards. It will probably be cheaper eventually, but it's easily worth $20.
Honestly, the question for cheapasses should be "Is Diablo 3 really worth three times as much as Rayman Origins?"
