Pretty much since 2k12 has no rookies for copyright/we own everything. Another reason not to buy 2k12
It's a shame with this lockout. 2K11 was probably the best sports game in recent memory and I've heard nothing but how 2K12 is so improved.
Oh well, though. I'll probably just spend that 60 dollars on Forza as I have NBA Jam to keep my basketball needs entertained. I highly recommend On Fire Edition (On XBLA and PSN) to anyone reading this.
