Wow, this is great! I've been wanting exactly this since learning perl. I've recently found UltraEdit to be a solid editor, but I long for the debugging capabilities of Visual Studio. I never thought Microsoft would actually support a community with predominantly non-proprietary leanings, though. Hopefully since ActiveState is writing it they'll stick to the IDE and not try to mess with the language itself. I checked the MS website and couldn't find anything either; the Next Generation of Visual Studio page doesn't mention it.
