No ZFS Support in Leopard?

InformationWeek claims that Brian Croll, senior director of product marketing for the Mac OS, has said that "ZFS is not happening" when questioned about ZFS's inclusion in Leopard.

This contradicts a statement made by Sun CEO Jonathan Schwartz during a speech last week:

In fact, this week you'll see that Apple is announcing at their Worldwide Developer Conference that ZFS has become the file system in Mac OS 10.

Prior betas of Leopard included evidence of early ZFS formatting availability. No word whether the WWDC build of Leopard has any signs of ZFS.
