I've watched Madworld very closely on Amazon (which I've found to be more reliable than people here believe) and saw it go from the top 10 briefly, then hang around in the 20's for a couple days, and now it's dropped off to the 70's.
Other games that follow a similar pattern usually open with ~20k or so NA sales. My prediction for madworld is 24k NA.
Games that crack 1m will typically stay in Amazon's top 20 for 4-5 months straight. Madworld has no chance of this. If it breaks 400k I'll be surprised.
I found NMH to be a more creative game, and I can't wait for the sequel.
