Ditto for the next DLC.
Buying the ones after that is acceptable, but for now Beth should pay for their participation in Microsoft's bribery.
I sympathize with everyone who doesn't have access to the DLC (especially PS3 users) but if you aren't going to buy the Dawnguard DLC, I would abstain from it for an entirely different reason. The DLC has some nasty bugs. NASTY. BUGS. I haven't ran into all of them, but enough of them to know that if they aren't fixed hastily, I won't be buying further DLC just to be sure I don't wreck my game.
It has already been stated that the bugs probably won't be fixed for the PS3 and PC release (PC users obviously less worried about this fact) but am I out of line for suggesting that it may be part of the reason they are delaying information? Maybe they really are going to implement fixes before throwing it out to the PS3 and PC crowd?
