Disc-locked is nothing short of annoying money-grubbing, but I'm not sure I'm down on the idea of placeholders for DLC that comes out later existing in the game. Not ideal, but acceptable, at least.
But then, I'm a fan of DLC anyway, and inclined to buy certain things for the titles I like. I didn't mind the Warden's Keep guy in Dragon Age, but I hated the cut missions in Assassin's Creed. And sometimes, we get some nice tasty treats reminiscent of the old ex-packs, but other times we get $5-10 affairs that are shorter, but are simply more of the game. The recent Fallout games did this, and while some of those add-ons weren't exactly the right mix of gameplay (lookin at you, Operation Anchorage), but other times they put you in a new map with all new toys to play with and plenty of skill checks to get your hands dirty however you like (see Mothership Zeta, Old World Blues, Honest Hearts, The Pitt, etc), and that's exactly the kind of thing I want to pay for more of.
