Sucks that Microsoft sat on the requests for approval for so long that Real Time Worlds gave up on the project (they'd already started developing it). It wasn't until RTW sent another game in for approval that MS responded (approving that game) and then ignored the correspondence asking what happened with Crackdown2.
Oh well, the new game looks to be a cross-platform MMO. Think Crackdown on steroids. Looks to be like they shifted what was to be Crackdown 2 and made it better, but MMO.
