Why does AD bother with desktop Compositors?

None of Autodesk's competition in the desktop compositing segment have the dilemna it does....that is concerns of it's lower end competing with it's higher end.

That's why Combustion isn't going anywhere, development-wise...nor is Toxic. There have been no ground-breaking changes in Toxic since it's first release, and neither receive much marketing attention.

Why not sell them off, the same way Avid sold XSI? I'd like to see what a company like Newtek could do with Combustion. Pair it up with Video Toaster, even.
