The title pretty much says it all. From the rumours floating around end of last year, its now confirmed and has a steam page. Release is set for Summer.

And as the link and page show, its a complete edition as well, so all the expansion and added content.
For me this is brilliant news and a really big thing for Sony to bring such an exclusive title into the
PC market. This will possibly be the biggest and best game news for me this year - even if its an older game to some; its one that I've never got to play (could never justify buying a whole console for one game).
