While not familiar with any of those games' online communities, I think it's a rather dick move to suddenly and inexplicably cut the servers without any announcement of the action prior. While it's understandable to cut programs that don't turn in a net profit, it's at least common courtesy to alert the developers and gamers still behind the community a month, or at least a week beforehand.
This just shows that the new GameSpy management cares even less for its community than the old one, which can't be good for the long run.
