For those unaware, back in 2016 CD Projekt told investors that they had 2 AAA games planned to release before 2021, Cyberpunk 2077 and a 2nd AAA RPG (which is rumored to be a Witcher game with a new protagonist, possibly Ciri). 3 years later, CD Projekt has just reaffirmed to investors that the game is still on track for release by 2021.

"As for the strategy of the CD Projekt Capital Group for the years 2016-2021, its plans for the release of the second AAA game until 2021 remain unchanged. We are currently focusing on the production and promotion of Cyberpunk, so we do not want to comment on further projects."

Man I hope this is true. Cyberpunk 2077 Q4 2019-Q2 2020 as a current gen title and Witcher 4 with Ciri as the main character Q2-Q4 2021 as a next-gen title would be so dope.

Aaaaand im already hyped for it.

Really would be awesome if it is another Witcher game already and would be interesting to see how they will improve on that franchise this time cause they always take such massive leaps when compared to previous games.

Yeah, it's hard not to be hyped, especially since it's likely to be a new Witcher game. 

Mmmh ... knowing the way they were managing their last project, I'd say it is unlikely.

Good, as I can't seem to care about Cyberpunk.

They can say whatever they want. I'll believe it when I see it.

With that said, even if they miss the launch window by a year or two, it is still nice to know that they're working on another big game.

There was ~4 years between each Witcher game so it a bit surprising they planning 2 AAA games within 2 years of each other. I suppose the one thing that make it possible is each Witcher game required a new or significant over haul of the game engine. It possible the unannounced game will be running the same REDengine 4 as cyberpunk 2077 or there will be a REDengine 5 but the changed will be more like between REDengine 1(Witcher 2) and REDengine 2 (Witcher 2 enhanced edition) vs the major overhaul between REDengine 2 and REDengine 3 ( Witcher 3).

Plus they probably have a ton of money now, so there are two different teams workin on games. If not three since the have Gwent as well, albeit a much smaller game that only needs supporting/updating now.

And they also doubled with the amount of devs working for them,CDPR is becoming a giant.
