PhysX 5.0 has been announced by NVIDIA to be available 'soon in 2020'. According to the makers of GeForce, this new version of the physics middleware SDK (which went open source about a year ago) introduces support for a 'unified particle simulation framework'.

Additionally, among the new features listed by NVIDIA for PhysX 5.0, there's the FEM simulation technique that AMD is also using in its recently announced FEMFX. It looks like games are about to get plenty of deformable physics.
