More import question is: Will they upgrade from QT4 to QT5?

I do not think MD will be doing that. I have the impression the Python API is not high on their list and they rely on development by an external party. I wrote the MD side bridgehead the way I wrote it, linking in one layer below the level they suggest, The level they suggest to use is/was plain buggy. I heard of no-one who used it with success.
Note that the API came with MD7 in fall 2017, yet they use Python 2.7. I do not see them changing unless they are requested by an important large client.

QT5 supports allmost anything one needs for fast 3D display and computing.

Maybe a RPC-Interface QT5 <-> Poser could be something.

Complete new Poser interface based on QT5, right? You could propose this to Jenn. ;-)
