The tax credit is going to happen. It's just a question of exactly how much it will be. I found this link in another post:

http://www.hybridcars.com/tax-deductions-credits.html

and for the HCH II CVT they estimate a credit of $2100 for next year, which is far better than a deduction of $2000, which is what it is this year. There are also links to official IRS sites etc.
