First off here is the link to the confirmation from Bioware/Mythic's top boy in an article over at massively.
And now if you cba to click the link, here is the info:
In a recent GDC 2010 interview with UGO, BioWare's Dr. Ray Muzyka said of Warhammer Online, "Right now it's [a] really profitable business unit within my group." Muzyka went on to say they've actually seen more people come into the game since enacting the free-to-play model on the game's earlier levels, and that he personally felt they were working.
In fact, by the sounds of it, Warhammer Online is due for some interesting announcements in the future. Another of Muzyka's comments on the title was, "We have new content planned and all kinds of cool expansions for it." We don't know how much more clear cut a message can be than that. And hey, it's good news! We're looking forward to our playable Skaven and Lizardmen, Mythic and BioWare.
Oh yea of little faith! In your face doubters! ;) Though I bet the usual negative troll brigade pick holes in this, even though you can't get much more of a solid confirmation.
