>>3807909 (OP)>new openMW release can run newer Bethesda games now.This is incorrect.
OpenMW can load most audiovisual assets from newer Bethesda games, but no actual gameplay elements are functional because nearly everything in OpenMW is still hardcoded to work for Morrowind specifically. It's been an ongoing process to port all the gameplay code from engine-level C++ to Lua scripts so that people in the future will be able to change the gameplay code to work with more recent Creation Engine games, or to make their own new games entirely.
Oblivion is the game most similar to Morrowind so support for it will come first, but it's likely at least a few years until it resembles anything playable unless a bunch more people suddenly start contributing to OpenMW's source code. Porting Skyrim/Fallout 4 to the OpenMW engine will be a whole nother ordeal because it uses a completely different scripting engine (Papyrus) than the Morrowind-New Vegas era CK games used, so even after Oblivion and FO3/NV become playable, it will be another few years on top of that for Skyrim/FO4 to get support.
Supporting newer Bethesda games also isn't the main priority of the OpenMW devs at the moment, they're still focusing on stability/bugfixes/mod support and replicating all the obscure quirks that Morrowind's GameBryo engine has so anything that has to do with non-Morrowind games won't see much progress. Trying to get newer Bethesda games on OpenMW is just the side project of a few OpenMW devs.
I really look forwards to playing ultra-modded Skyrim/Oblivion/New Vegas on OpenMW and seeing what those games' modding communities would be able to do with it but realistically that is close to a decade away.
