Just a note for the future: When removing a feature many people are relying on, it often pays of to have the replacement ready. I get the feeling that essentially disabling Steam and Wine and telling people to hold of on playing games for a couple months is going to drive many people away.
I understand that there is too much to do for too few people, and dropping features you don't feel are needed seems like a good option, but you are also serving a community of users. Telling a portion of that community that they are not wanted and should go elsewhere seems like a bad strategy, even if it frees up development time.
Personally I'm going to hold off on the 1.3 upgrade for as long as possible, and see how that turns out.
