Estimated revenue increase when game is released?

Right now Chucklefish has received almost half a million dollars from pre-orders, and that amount of money will continue to rise at a pace that will get slower, and slower.

My question is, how much more money do you think they will make in the first month or two when the game first comes out? Or, how many people do you think aren't going to pre-order, but will buy the game?

I'm just curious about this, I know that the number is going to be high, I'd just like the communities opinion on this.

 

*obvious dr evil quote*

But really though. Several of those.

 

i realize that a lot of people have already purchased the game for themselves and their friends but then there's this whole other side that the game hasn't touched; i'd say that an equal number of non-preorder and pre-order for a bit fallowed by more full purchases. me no like numbers so no number estimates from me.
