I know nothing, but I am seriously guessing that at this point 80% plus of BFCs effort is towards Normandy. Which I will surely enjoy immensely when it comes out.
For my own two cents I would prefer a vast expansion of CMSF to cover Iran, Pakistan, Afghanistan, and perhaps the drier parts of the ongoing Africans disaster zones. I would pay 25 bucks just to get a good tactical treatment of drones. But if Normandy is what will produce the most active multiplayer community, and by extension sales for BFC, I can go with it. And enjoy the expansions they do make to CMSF in the meantime.
