The valve coupon I have says it excludes games that come out after 01/02/12 so yea even if by some miracle HL3 did come out soon into 2012 the coupon ain't going to help.
My question is can I get the ps3 version and then do you get a code in game to access pc version? Than can I sell my ps3 version for high resale and basically get a free copy of portal 2 on my computer...or do they require you to keep the ps3 version?
