I work quite a bit with green screen keying. I see the same keylights, ultimattes and primattes used still even in big productions I have worked. Fixing the key can take weeks. Maybe industry is bit conservative and I haven't seen cool new stuff bubbling under, but would love to have new tools in the toolset to approach difficult shots.
