As I recall Sony talked about releasing Galaxies on PS2. That fell through as well. As said, it would probably be impracticable to bind all actions to a few keys - unless we are to pause and select an action from a menu. Which would be awful.
As much as I would prefer the better graphical quality of my PS3 (as opposed to my own computer), it seems better to keep it on PC. It would likely have much more range and depth than would be possible with a console.
