In an interview with Jason Schreier, Marcin Iwinski confirmed that Cyberpunk 2077 will be present at Gamescom 2018. Marcin also said that Cyberpunk 2077 will be powered by the next iteration of the RED Engine, called REDengine 4. Marcin also claimed that this demo was not a fake one, was not built entirely for E3, and it was a real build of the game.

When Jason Schreier asked about the E3 demo, Marcin had this to say:

“The demo, it’s not a demo-demo in terms that it’s an artificial piece of content created for the purposes of the show. That’s actually a build of the game… actually, surprising it is a real build so we didn’t fake anything here and actually we had a lot of… we didn’t start these conversations but we had a lot of feedback like that in the previews by people actually noticing that certain things did not look pre-rendered or fake. And this makes us very happy and very proud because we’ve actually made it to pull off a build.”

And then, when asked about the next event in which Cyberpunk 2077 will be showcased, Marcin confirmed that there will be a demo at Gamescom 2018, though he did not confirm whether it will also be behind closed doors or whether it will be showcased to the public.

“I think we still have Gamescom so we’ll be showing it. I can’t tell you that [whether CD Projekt RED will be showing something different than what was shown at E3 2018] but it won’t be the same, it will be worth visiting. Of course do not expect a totally different demo please… but we will show maybe something different, maybe some different angle.”
