As Mario notes, it's not a done deal yet. Also, your info. on the extension is a bit different than what I have read.

Senate Dems on Board with Credit Extension
Senate Banking Committee Chairman Chris Dodd (D-Conn.) says Senate Democrats have agreed to extend the first-time home buyer tax credit. The latest version extends the program to home sales signed - not closed - by April 30. Purchasers would have another 60 days to close the sale. The credit will also be expanded to include so-called step-up buyers who have lived in their current home for at least five years.
The credit would be cut nearly 10 percent to a $7,290 cap. Income eligibility for first-time home buyers would stay the same, but it would rise for step-up buyers to $125,000 for individuals and $250,000 for couples.
