I already checked the three Burger King games (Sneak King, Big Bumpin', Pocketbike Racer) and those are still unsupported for HDD installation. Crackdown suffers from the same fate as does NBA Ballers: Chosen One. It would be safe to assume, then, that the rest of the uninstallable titles remain that way for the new NXE.
BTW, where did you hear that Crackdown was going Games On Demand?
