Well Montana if thats the case then maybe they're subscribing to the 'throw enough crap at a fan and something is bound to stick.' Besides w/o knowing production values its hard to quanify a flop. And according to some devs the cost to port is only 10-15% of the orriginal production cost. I'm sure even the 'flop' numbers of Zack and Wiki would be profitable on the investment.
As far as the buzz, there is a lot more word of mouth about how good okami is now than when it was readily available on retail shelves.
