That article was written after the first day of Mix. Silverlight 5 features weren't to be announced until the Day 2 keynote, which was almost all about Silverlight (on the phone and the web).<p>Microsoft's position on HTML5 and Silverlight seem extremely clear to me. If you're doing cross-platform their focus is now HTML5. You won't see much of an investment on Silverlight for the Mac, for example. But if you're developing exclusively for Windows, then Silverlight is your best bet.<p>Regarding WPF at Mix -- Mix is a web conference and WPF is NOT a web technology. Expect WPF sessions at PDC (a couple to a few at most), although I do think that WPF and Silverlight are merging (with Silverlight basically just catching up to WPF, with WPF being left to handle niche Win32 interop scenarios).
