The Adobe Products website doesn't mention Freehand MX though it has links for all other Macromedia Products. And now a recent FreeHand to Illustrator Migration Guide posted on the Adobe Design Center just confirms that the days of Freehand MX are numbered.
Once Adobe eliminates Freehand MX in favor of Illustrator
My suggestion is that either Adobe sells the product to another Vector Illustration software company like Xara or every better - make Freehand open source - let the community handle further development of Freehand. This will cheer the Freehand loyalists, Adobe will win the heart of OS community and a great product like Freehand MX will continue to live forever.
