According to some reliable sources (meaning that Square announced it and I read it at GamesAreFun), Gackt is in Dirge of Cerberus. He's apparently going to give his likeness to an "important character", have some of his songs in the game, and wear the clothes that Tetsuya Nomura designs for his character on his next tour.

I'm not sure what to make of this. DoC is already looking very questionable, and now they're bringing Gackt in for no reason. Well, on the positive side of things, Yuffie looks really hot in DoC. Seriously, have you seen the screenshots? I mean...wow.
