Three Witcher games in six years and a CP2077 full blown sequel developed in parallel.
Sure, sure.
None of this is going to happen.
The Witcher games are being developed in Poland over the course of ~6 years (150 devs currently on the project)
Cyberpunk 2077 Phantom Liberty on track (350 devs curront on project)
Cyberpunk 2077.2 is being developed by CD Projekt Boston.
All projects are likely Unreal Engine 5, they have a partnership with Epic so Epic is probably providing quite a bit of support.
People forget how big CD Project Red as a whole actually is....they have over 1000 employees.
Thats a massive massive set of people to work on multiple projects, not even counting once you start outsourcing.
