The Polish interview you mention is new to me, thanks. Do you remember when that happened? Don't get me wrong, I agree that both Gwent and Thronebreaker would be perfect fits for the Switch, especially given that Thronebreaker did not seem to do well on other platforms, which is really a shame.
I've been following the Witcher 3 port rumors for a while. The sole detailed and convincing technical analysis I've found concluded that it would be possible without sacrificing atmo ONLY IF they seriously invest in-house into the port, i.e. changing textures, removing superfluous effects, grass detail, lots of optimization, etc. The question is whether they see a market (which I would claim exists with millions of people literally buying that console for the other mature open world game of the decade, BotW) and want to invest their own resources into such ventures right now.
Expecting Cyberpunk is unrealistic, that game even looks too demanding for the current gen.
