CD Projekt finally showed off what it's been getting up to with Cyberpunk 2077 at E3 earlier this month. The demo was behind closed doors so we, the people without appointments, didn't get to see it for ourselves (you can listen, though) but by all reports it was good. Really good. All of which might lead you to think that the full release of the game isn't too far off.

Maybe it is—anything is possible—but it doesn't sound like that's the case. Following a similar presentation this week in Warsaw, according to a Bankier.pl report (Google translated), CEO Adam Kiciński described the demo as being "earlier" than alpha and "not the final quality yet," which is why it's not yet being shown to the public.
