Lots of developers have been having problems with 2011’s summer season – Serious Sam 3, for example, has gone from “summer” to “22nd November” in no more than a few months. L4D2’s Cold Stream DLC went from “summer” to “around Halloween” in also just a couple of months. As for Portal 2? “Summer”, then “mid-September”, then… nothing. Has the entire DLC been lost into the sinister swirling vortex that is Valve Time? Apparently, and surprisingly, not really.
