Not sure if that's news, Audio Modeling[1] has been doing that for quite a long time now. The big plus of physical modeling instead of sampling is disk size - instead of tens of GB of samples, you get a 15MB plugin.
It's much more difficult to use, though - you have to control lots of aspects of the simulation (using automation in DAW or MIDI controllers) to make it sound actually realistic.
OK I guess it seems like this is more of a tool for luthiers than for composers or music producers.
The first version of Pianoteq came back in 2006. There are apparently some exotic mid-90s synths with claims of being physically modeled too, don't know how accurate that is.
I currently use a raspberry pi with Pianoteq as sound output for my digital piano. It got a reluctant stamp of approval from my pianist son, although of course he prefers the physical response of even a poor acoustic piano.
