The N3V Games Website now lists February 18, 2010 as the Australian release date for S.T.A.L.K.E.R.: Call of Prypriat, GSC Game World's upcoming first-person shooter sequel. This may be a hint about when to expect the game in North America, where it carries a Q1 2010 release window. Thanks The Patches Scrolls.
Hopefully it's not just localization, but also additional polish time. GSC might subscribe to the idea that North American PC gamers are a little less forgiving of bugs and other issues than their European counterparts.
