Liberator wasn't "cut". It was created as July 4th DLC and "locked" until July 4th. Bonus news flash: Most, if not all, DLC is already on the disc and was created and coded alongside the rest of the game...
If it were already on the disc, people would've found everything already earlier... pay more attention.
And I'm on the side that insists that what we're getting is not DLC. DLC is something that, free or not is downloaded as an optional pack for the game. What we keep getting are mandatory updates, and the only way not to use them is to refuse updating (which won't let you play Online, of course).
