They mentioned in one of the previous streams that they're planning to do a Thronebreaker stream as well. if that is indeed the case, then I'd expect that to come before the Cyberpunk one.
Will be interesting to hear from Miles, I think the level design team did a very good job with Cyberpunk, managing all the different gameplay options the player has in tackling an objective. Night City as a whole was also certainly a highlight of the game. And The Witcher has of course always had very interesting locations throughout the series as well, although probably less complex from a level design perspective.
