Interesting to read THQ's Danny Bilson comments....
Would appear finance wise they sticking to budget if 1 million subscribers enough to make this viable. Watching the trailer almost looks like wow over imposed with 40K themed graphics.(WOW) They've got 14 million players! Gimme a million and I'm good! We're real good at a million, right?" -We don't need everybody to migrate. We just need some of them - and I'm full confident we're going to get them.
Despite not being a fan of mmo's, i think the 40k franchise (despite having spent early youth working for GW ) is great and may have to take a look at this if it works out well.
