Hello,
I hope that VSL does not abandon VIENNA INSTRUMENTS PRO. I am not yet used to the Synchron player (except for pianos) and VIP has fantastic functions that are not found in Synchron. The customer has also invested a lot in VI with the purchase of instruments, which has contributed to the development of VSL.
So VIP has to go to VST3 and iLok. VST2 is no longer supported by Steinberg, as you know, and the eLicencer system is a horror (no instruments yet this morning..., you have to clean it often!, and it crashes DAWs).
I hope it's in the plans. You can't abandon a flagship product like VIP.
