Shacknews has an explanation from Valve writer Chet Faliszek that Valve actually intended to release the "Crash Course" DLC for the original Left 4 Dead prior to E3, which might have tempered the unhappy reaction to the Left 4 Dead 2 announcement, "but some things held us up." The L4D2 brouhaha might have also been lessened had they mentioned this at the time, but Chet says: "We just didn't think to mention it, we were focusing on other stuff," which he acknowledges was a mistake: "I think if we had that out before the Left 4 Dead 2 announcement, then it would have been clearer for our intentions. Losing the opportunity to get that right hurt us, but I think we made the right choices otherwise."
