MS Nerd pretty much confirms what us "haters" have been saying all along. SL is dead (and indirectly WPF). They also seem to draw the line between desktop and WinRT/Metro; sounds like the desktop is dead too. And XNA? Gonna be dead sooner or later. Everything is going WinRT.
Sure you can still develop against all of the dead technologies but you can still also write stuff in VB6.
If this is true they're drawing a pretty hard line with a big bet on everything flipping to W8 and WinRT. No compromise for sure.
