Found a couple of interesting threads on Reddit. It may be that two expansions are coming. And plenty of free DLCs.

However, remember these are leaks and not official information from CDPR. Take these with a grain of salt.

My guess would be...

dlc8_mirror -- V can be seen in mirrors. (Especially immersion breaking when you carry a body next to a reflective surface and in the mirror you just see a body floating in air.)

Expansion 1's Combat Zone is probably related to dlc10_monster. Perhaps something from Cyberpunk Red: Combat Zone and Monster Fight Club.

dlc1_swp, dlc7_pwp and dlc13_twp are probably smart weapons pack, power weapons pack and tech weapons pack, respectively.

dlc15_ngplus is pretty self-explanatory.

(And remember: rumours, leaks, guesses... nothing here is official info.)
