CD Projekt has posted more details about the projects, that will be partially funded by the Polish government.
The most important part seems to be the timeline for all 4 projects (that is seamless multiplayer, cinematic feel, animation excellence and city creation) -
they will run from 01/2016 and 01/2017 until 06/2019. It's important to note, that the funded projects should be released by that date, but CDPR can apply to have those deadlines extended.
All of the projects will be included in
RedEngine 4, the next iteration of the RedEngine.
