WTF?!
Famitsu noted that the lighting effects in the Pit Menu screen are particularly impressive, and Yamauchi responded that the game uses a technique called High Dynamic Range Lighting. He believes that this is a technique that cannot be replicated on other systems. He also pointed out that the scenery used in the pit menu is actually an evolved version of the same scene from the GT4 intro. Of course, the scene was pre-rendered footage in GT4, and it's real time here.
I think IGN may have left out a few keywords (before or after) during the translations of the Famitsu article. BECAUSE...XBOX 360 CAN DO HDR!!
Lol I believe so to but if not then he obviously hasn't heard about xbox360 or PC (if so then 'shakes head')!
