Traditionally developers have tended to lead on one platform over the other, with the majority first developing on 360 before porting over to Sony's PS3. L.A. Noire was originally mooted as a PS3 exclusive which suggests it was the lead platform, and history dictates that games ported the opposite way around tend to perform poorly on the Xbox 360. But, if anyone has the resources to buck that trend it's Rockstar Games, so we'll cross our fingers and hope both versions run flawlessly. Especially after the recent furore surrounding the PS3 version of Call of Duty: Black Ops with its alleged terrible online play, compared with the Xbox 360's seemingly perfect online.
