Boon's realized that people hate it when you announce dlc before the game is out. I would be 100% behind him, but on one condition.
Do not pre-sell kombat packs when you don't describe the content thoroughly. No 100$ editions. Just the regular 60$ buck edition, and announce the existence of dlc at least 3 months later. That way the theory that you are willfully holding back content can be harder to prove, and dlc haters won't bitch at you so often.
But I guess WB really wants those 30$s.
