Northrup they hare doing the alterations to allow it. Hypervisor allowing many versions of windows to be run side by side. Everything I have seen Windows 7 is not really to make the jump. Windows 8 maybe. You have another nice issue. Wine is tested a lot with gcc almost none with MSVC. So things could get really interesting. There are a lot of other things that will make doing it hard Northrup. Ie MS posix layour all times recently I have looked are way out of date compared to current day posix standards. If it was upto date the would be a good chance wine could be built there. Thinking the MS posix layour has a gcc complier. Also wine is C. And the issue wine has with MSVC are not really C++ relegated. Gcc and MSVC have different ammouts of standard incompatibility.
