It doesn't look like Activision and Harmonix are ever going to make nice and implement broad hardware compatibility for Rock Band and Guitar Hero controllers, but if you've got a sizable investment in PS2 gear, The Ant Commandos' new converter might let you ignore all the nastiness and keep rockin' anyway. TAC's Universal PS2-to-PS3 Converter is compatible with PS3 Rock Band and PS2 / PS3 GHIII, and it works with basically every PS2 axe you can think of, wired and wireless. Not bad for just $20, but c'mon, guys, let's just make this stuff work for real, alright?
