I have the same question. If I remember right, it's going to happen in 2020.
I don't work with a studio yet but studios who buy the software don't seem too worried for some reason, even though their pipelines depend on it. Maybe someone else can offer better insight. As someone wanting to go into pipeline development, I am very curious.
Nice! Thanks for pointing this out. This could be naive but maybe the script transition can be a hiring opportunity for those like myself... not that there are many of us.
