For those fluent in the Polish Language, please tell us what this is about, but
according to this post on NeoGaf, the
video is about a game that is further in development than
Cyberpunk 2077 and is likely to be
The Witcher 3.
Sorry for bumping but I watched an interview with the CEO of CDPR and he confirmed that The Witcher 3 (he didn't say Witcher 3 but the second project) is much further along in development than Cyberpunk 2077 and will be announced in the first half of this year. Interview is couple of weeks old but I don't think it was already posted here and some of you were curious which RPG will be released first.
More information.
