Rumor has it as first quarter 2010. It probably depends on how the release of v.5 goes and how early it gets out. I heard February from someone who was at a convention in Louisiana, but I've observed that, in general, big software releases slip.
(I don't want to rumor monger in a bad way. I suggest we not get too tied to their internal goals lest we be needlessly disappointing if they slip three months.)
