CD Projekt Red has recently applied for these technology grants; Seamless Multiplayer, Animation Excellence, Cinematic Feel and City Creation, from the Polish GameINN program (which helps fund game developers). The grants give a basic idea of what features we might see in Cyberpunk 2077.
The most interesting applications are; City Creation, which is "a complex technology for creating a huge living city, playable in real time, which based on rules, AI, and automation, and supports innovative processes and tools for making top-notch open-world games" and Seamless Multiplayer, which is "a complex technology for making unique multiplayer gameplay mechanics, including the ability to search for opponents, manage game session, replicate objects, and support for different game modes along with a unique set of dedicated tools".
PC Gamer contacted CD Projekt Red to confirm the news, to which Robert Malinowski replied; "We did apply, I can confirm that, yes. However, we wouldn't like to elaborate beyond what's already there."
