That's still the lamest excuse I ever heard. Why just deaf folks, Valve? Why not tailor your games to quadraplegics and to those in vegetative comas? What about the recently deceased? (Oh, right, LFD. Never mind.) Point is, the only viable reason to delay Episode 3 at this point is to make damn sure it's a lot better than Episode 2, and any other reason is beside the point.
Flame on, people. Flame on.
