In an
interview with the VP of Product Development at Rockstar, Jeronimo Barrera cited the PS3 as a contributing factor for the delay of
Grand Theft Auto IV. The two console versions are back to being in sync now so things should go pretty smoothly here on out. Not surprising as the console is a different beast to program for but it does confirm the rumor that this was one of the reasons the game was being delayed. Also, the 360 version WON'T require a hard drive so those that still have the core and arcade system can play the game fine.
