The following was against it from what I read around the internet:
1) year later than 360/PC versions means many who had access to those systems played it
2) Despite it being new to PS3 many clearly felt it was too much to see a full price tag on the game when the 360/PC versions were probably only a few shelves away and showing a much lower price
3) It was seen as a 360 game and was shunned by certain PS3 owners
4) It (unfairly really) got branded as being worse than 360 version - I say unfairly as the only thing I saw was a few errors with some textures which were sorted out quickly with a small patch
I doubt 2K are that disappointed with the sales, though. I suspect the move was more to get the franchise on PS3 ready for a true multiplatform release for number 2.
If they wanted more sales they needed to release it at a lower price.
Try to be reasonable... its easier than you think...
