I honestly don't think it's TreyArch - I think it's Activision. TreyArch takes orders from Activision. Hell, I imagine Activision takes orders from Microshaft with all their exclusivity clout. And I still think Nintendo is pissed at Activision for how they wouldn't pony up for all the Wii's BO1 broke (mine was one of them - had to send it in, got it back fixed with a brand new copy of BO1). Maybe Nintendo put them in time out this round. I think DLC griping should be put on hold until we find out if they do it for Ghosts or not. I give them a pass on the first game for the new Wii U.
Support is bullsh!t though (still waiting for that patch they promised a couple months ago that was "ready to go"). Dev involvement in the community and support (patches) shouldn't stop this soon.
