In an interview with Digital Spy, Portal 2 writer Chet Faliszek stated, ”We have a DLC that we’re going to be announcing. Really can’t give you any detail (until) after launch, and we’re going to have some details about how that’ll get released and what that’ll form forthcoming.”
Faliszek was cagey when asked if the DLC would be in the form of new levels, saying only ”We’ll see”.
He also added the Steam support for the PC, Mac and PlayStation 3 versions would make patching easier. ”It’ll let us update more frequently, which is a big thing especially because the PS3, PC and Mac can all play together,” he said. ”And so why they might not get every single patch as some are PC-dependant or just for the PS3, it’ll let us keep those in sync so they can do the cross-platform play. So that was the most important (thing).”
Portal 2 is due to be released on April 19 in North America and April 21 in Europe for PC, Mac, Xbox 360 and PlayStation 3.
