Hoping Crackdown embraces character creation. I'm also eager to see how the destruction system is coming along. It will live or die off its traversal mechanics, though.
That next gen destruction combined with precise and fun platforming could mean for something really special. We've got the original creator back for CD3, they've been given lots of time, money and more importantly have a solid foundation to build the game from - at the very least i expect it to be better then CD1. Minimum.
IMO they're most likely spending a lot of time on multiplayer, turn this in to something huge.
