Since Steam is porting to Linux can we hope of ever getting linux versions of these games? Bethesda games are the only reason I still have Windows........

LOL. Yeah, uber-nerd in me too would love for a Unix/Linux market to open up. But until/unless the GUI is everyman accessible and marketing improves, I fear your niche is way too small to dev for. Hence, I too use Windows, even as a dev plat, since it just makes everything that much easier to test from the end users' perspective. So far, just running Safari under Windows allows for web-based dev for Mac/iPad, but who knows if that will change as well.
