That's highly unlikely before version 4.x (and might be tricky even then, for various reasons) because so much of the 3.x code heavily relies on obscure Microsoft stuff such as MFC for the frontend. It'll take a complete overhaul before this is a realistic proposition, but luckily the problematic parts of the code are quite a nightmare to work on even on Windows, so the devs certainly are motivated to get rid of them and get things right in the rewrite!
