I would be giddy if Dark Could 3 is made for the PS3
They did a wonderful job with cel-shading for DC2 on the PS2, I would love to see what they could do with cel-shading on the PS3. They could also really kick it up a notch in the town/world building aspects.
I also wouldn't mind Rogue Galaxy 2, or something similar, but I'm not holding my breath
