Remixed music? Like the shitty remixes in Dracula X Chronicles? No, thanks—even if it is optional. Worst CV score ever, by a long shot; bastardizing one of the best in the series.
But so you guys know, an ESRB rating doesn't mean a release is imminent. I believe Kirby's Dream Land 3 got rated (from K–A to E) like a year or so before it finally came out.
