At this time there is nothing that I have seen that would extend into 2010. But I would assume that depending on what is happening with the nation's economy, there will be proposals for programs that may assist Buyers.
You may also want to find out if there are any local incentive programs, or assistance programs for 1st time home buyers. I know here in Milwaukee County they have downpayment assistance programs for buyers that are within certain income levels.
All the Best to You!
