SplitFish's controller replaces the right hand side of the PS3's joypad with a mouse, complete with familiar buttons and a grotesquely large mousepad. It's a follow up to their EdgeFX, a PS2 controller that looks very similar. The difference? This has SIXAXIS control on the left hand side. PS3 could be developed to handle the variable mouse inputs — supposedly, this'll work well for navigating in Home. Their latest 1.6 update, due on Thursday, is getting Bluetooth mouse support, too. And this comes in both USB and Bluetooth flavors. Could be an unfair advantage in games, although I doubt widespread support will go very far.
