If you are going to do that why not make an "easy" to use DelphiX. Get rid the broken 3d stuff that never made sense and is now done so much better by others.

And instead concenrate on the reasons why people want to use delphix - easy to learn lots support. Make sure delphix continues tol work with DirectX 7 - this is one great reason to still use delphix. Programs you make using delphix will work on just about all computers out there.

No point competing with the new systems and lose what made DelphiX so useful.
