Rick,
The best information you've received is to speak with your tax professional. I'm not a tax professional but was able to find this website that may provide some information.
Here is the link to the IRS page with updated (more coming?) information.

With just a quick glance, there is no information about 2010 purchases.
There is a remark on the IRS form
"We will soon issue a November 2009 revision of Form 5405 for claiming the credit for homes
purchased after November 6, 2009." I'm not certain this will cover 2010 purchases.
