[quote name='crzyjoeguy']i think they have the ps3 version cheaper because i believe, (i am not 100%) but i believe the 360 version sold alot more, and is still selling better then the ps3 version, so that could be why they dropped the ps3 and not the 360, but again im not 100% sure i am correct on that[/QUOTE]
This is most likely the reason, as games like Oblivion ($18 vs. $27) and GTA IV ($20 vs. $35) are considerably cheaper on the PS3 at GS also.
