Halflife2.net has word that Valve's Half-Life 2 expansion - "Aftermath" has been delayed to Feb. - March of next year:
Doug Lombardi: "Just wanted to give you a quick update on Aftermath, specically its
ETA. We're working very hard to finish this new episode for HL2,
however, its going to take us a bit more time to get it into top shape.
As such, the target release for this one is now Feb/March of next year."
It doesn't bother me very much, as we saw with HL2 that waiting turned
out to be worth it in the end. Valve hasn't been promoting this
expansion much either, and it doesn't seem like there's much hype yet.
