It's one of the ideas being tossed around before, taking advantage of the 20/60GB HDD in the PS3 to cut loading times. Sony confirmed during Gamers' Day in San Francisco that the launch title Genji 2 (Genji: Days of the Blade) would use the HDD to cut loading times, as reported by MTV News.

As detailed by MTV News, all you have to do is wait three minutes for the game to upload 4GB of game data from itself (or the Blu-Ray disk, at least) to the PS3 HDD. Sony says that this will cut down game loading times from fifteen seconds to four seconds. People may have different tolerances for load times for different games (personally, fifteen seconds is not too bad for me), but what's definitely been demoed before is the HDD-load option there, and it's available for developers to take advantage of, if they want to.

Okay, so fifteen seconds or four seconds later, what do you get? Courtesy of GameVideos, this preview of weapon-swinging, butt-slinging action from Game Republic's and Sony's Genji: Days of the Blade.
