Yeah. If you read further, it says that "Microsoft has no current plans to remove Linux support within Virtual PC for Mac" - but what about future plans? If Microsoft integrates Virtual PC more closely in order to present their Windows software more integrated on the Mac (without having to port everything), then certainly some compatibility will be lost. Of course, at the moment they have no plans for that, after all the whole thing was just bought.
I wouldn't bet on Virtual PC as a long-term solution for Linux anyway. However, Mac-On-Linux running under Linux on the Mac (natively) is the nicer solution anyway, and Microsoft doesn't make a penny from that.
