I hope Ryo comes to PS3. Even if it's paid DLC. Would also be nice to get some of the PC characters but that might be a stretch. To me that would be like getting a whole new game.
If by chance the game's sold well enough to justify another run of physical copies, they should release a "Super" edition on consoles with all the DLC on disc, since I gather it's all been PC-only thus far. The additional content could be enough to get people re-buying the game (at the right price) after parting with their copy of the launch version.
