Sweet!
Microsoft announced that they're dropping WinFS from Longhorn, and shippin it in 2006. This is good news; hopefully they've designed it so they can add WinFS in an update.
Better news is that the same announcement promises that a lot of the new Longhorn technologies will also be made available for Windows XP.
This means like Avalon and Indigo and Xaml go from being interesting curiosities that developers couldn't really justify, to technologies that they should start becoming seriously interested in.
Time to get Xamlon and start playing...
