It was funny to see all the Silverlight devs go mental about the fact that MS was mostly silent about Silverlight at PDC, whilst talking a lot about all their "HTML5" stuff. This is just a repeat the last couple of years, except then it was WPF getting "killed" in favour of Silverlight.
In actuality, of course, both WPF and Silverlight are doing fine. It's just that development and announcements scale back as the platform reaches maturity. Yes, Silverlight has a couple of features that I *really* wish were in WPF (as a full-time WPF developer), but in general it's a fantastic platform. If you look in the right places you can see that they *are* still adding features, they're just not great features to show off in a keynote (cross-thread collection binding! woo hoo!).
I'll be interested in hearing today's announcements, though. (And I do wish the WPF team wasn't *quite* as "dark" ATM).
