Yep, I know it's a bit out of my normal area these days (though a couple of years ago I got to learn the metro line very well) but Denny Boynton is putting it together and since I still have a number of folks I talk to in the area, I thought I'd drop an announcement about it.  You can find the details at the above link, but this is the equivalent of the XamlFest that happened in Houston last year, and an expanded version of the Dallas Silverlight DevCamp that happened a bit ago.  If you're interested in seeing how to really make use of XAML and happen to be in the area, it's a great way to get up to speed on a technology that'll be useful in all manner of UX's, even such really new platforms as Live Mesh!
