Has nothing to do with piracy IMO. Although the patches for Xbox and PS3 came out very late, too, the release date of the PC patch simply is a joke. They more or less have buried the PC version last year as they saw that they weren't selling enough copies. That's also the reason why there was not 2k13 for PC. They are traditionally very laze/late regarding patches. It's the same with the NBA series.
Why should they bother piracy when nobody is interested in the game whatsoever?
