There will be save hacks for that one. Resident Evil 5 was the same way then a hack came out that would let you log into windows live (from another account offline) and save. This will happen here. I wonder when companies will realize that their fail drm doesn't work and discourages us from actually buying their games.
Chronicles of Riddick Dark Athena was the same way. Had a shit ton of drm and look at the reviews it had from amazon when compared with the pc to console versions.
