Are there going to be music products from Microsoft?

This appears to be one-month old news, but I heard just lately that Microsoft is planning to introduce products that are geared towards musicians. Since most "The" music products are on Mac, it would be nice to have some real broadliner like Microsoft to have their own products as well.

Enter code-name Monaco. This could become the Windows version of Apple's GarageBand application. Do we get Monaco on MSDN once it is ready? :-) I'd be one to download it immediately.
