Resurrecting Wings...

[micheus]

The biggest problem with Wings' developmental acceptance and adoption has been the fact that it was written in erlang.
...
Your best bet, as a developer, is to try and port the Wings methodologies to something like Blender.

Well, that can be true in a long future.
For those who have lost the Wings clone in C++ thread, they have been working for the last two years and maybe this year they will release the first beta.

Maybe we will be able to know if the language is/was really the problem to not have more people engaged.
