Sure, the Blood and Wine expansion is about to be released and officially CD Project Red is done with the game, and we also know Cyberpunk 2077 won't be out for a couple of years.
However, that doesn't mean they won't have something else to show on E3, and in an interview CD Projekt Red boss Marcin Iwinski says:
"We still have a lot of work to do with Cyberpunk. It might happen that we will be at E3 and we will show something at E3, but I just want to make it clear it's not Cyberpunk."
Intriguing.
