This is a huge threat to Adobe, as Microsoft's XPS is going to compete with PDF as a format.
It's only a huge threat if they ignore it. The monopolistic power of Microsoft has started to fade at an ever increasing rate; the deal with Novell shows that. Adobe has a good and very popular format; it's theirs to loose more than it's Microsoft's to take. By opening the standard their position should be safe for a while. That said, turnabouts can come very quickly, if there is a good reason.
