Quoted from ARSTechnica:

The so-called next-gen filesystem to come from Microsoft is really looking to earn that generational distinction, and in more ways than one. Not only is the tech promising (what we know of it), but apparently it's taking much, much longer to bake than we thought. Originally slated for release with Longhorn, it was revealed in April that WinFS was being scaled back, and wouldn't make the Longhorn desktop release. Later in August we received official word on the matter from Microsoft, who then said that they planned to release WinFS as an off-cycle development platform. Then, in late October, Ballmer said that WinFS would ship with Longhorn Server, and be available as a free add-on for Longhorn.

Yesterday Bob Muglia, Senior Vice President of the Windows Server Division, told press conference attendees that WinFS would not ship with Longhorn server, but would be delayed even beyond that. In general terms, this puts WinFS into 2008, at the earliest. Muglia has some regrets about having pumped everyone up for something that's getting pushed back on a quarterly basis now.
