I find it very strange that such a popularly liked type of game has never been made in recent years despite the large market for it.
There are plenty Cyberpunk games out there (Deus Ex, Fear Effect, etc...)
But a "Cyberpunk" game (in the "meaning" on the word, not just a random game with some cyberware and tall shinny buildings in it) requires a lot of knowledge of the universe and needs to be made with taste, just by that, I guess that's why Mike pushed off a lots of offer to adapt Cyberpunk 2020, they probably wanted to make a braindead shooter.
Also, a Cyberpunk RPG is wayyyyy more complicated to create than a medieval one (and even on Pnp, preparing a session require a lot more work, lot more details etc... to put in it), I guess we just "step" into the tech possibilities that may let us create a realistic Cyberpunk universe, you need a lots of social layers, a "street" feeling, etc...
That requires a lot of tools (even naratively) to develop it, and make it faithfull to the genre, it needs a lot of depth, and we still have to see if Cyberpunk 2077 has it.
It sure looks beautiful, etc... But how deep will we be able to go?
Will we be immersed in a futuristic setting, lifelike, stumbling over people with everyday problem we may try to help?
Or will it be a BIG shinny world, filled with "OMG the raiders stole my cyberware, go kill them at X place, thanks V!" (looking at you Fallout 4...), I guess it won't be that, but that why it's so difficult to flesh out a cyberpunk RPG, you need to put so much layers to flesh it out, it's a very difficult universe to adapt (even more when you're not used to it).
