Here's the official word from Adobe:

Adobe and FreeHand
Adobe does not plan to develop and deliver any new feature-based releases of FreeHand, or deliver patches or updates for new operating systems or hardware. Adobe will, however, continue to sell FreeHand MX, and will offer technical and customer support according to our support policies.

FreeHand Upgrade Path
A special upgrade to Illustrator CS3 is available to all registered owners of FreeHand for $199 U.S. This upgrade is available worldwide through the Adobe Store and through the Channel. There is no direct FreeHand to Creative Suite 3 upgrade, but FreeHand owners who also own Adobe or Macromedia products that are eligible for upgrade to the Suite can use that path to move to the Suite.

Support for Customers Making the Move
A number of materials are available at no cost to help customers make the move from FreeHand to Illustrator. All of these materials can be found on the Switch to Illustrator pages on Adobe.com

(www.adobe.com/products/illustrator/switch/)

and on the Illustrator Design Center ( http://www.adobe.com/cfusion/designcenter/search.cfm?product=Illustrator&go= Go ).
