God, Ciri looks so fucking weird. It's like they put a 20-something-year-old's face onto the body of a 10-year-old.
Aside from the hair colour she looks REALLY similar to a chick I used to work with who was 14 (Ciri in the Prologue would be somewhere around 12-13), and both of them look very appropriate for their age, so I very much disagree with your assessment, but opinions.
As for the topic of graphics, I am legitimately shocked at how great the PS4 version looks in those videos. It's nice to see it with a decent capture card quality, and Kaer Morhen looks stunning. Not just aesthetically, but graphically too.
We know that the PC Version has graphical notches higher than what we're seeing there on the PS4 and there's all the extra little dongles that PC has (HBAO+, Higher Resolutions/AA/AF etc).
I think abso-fucking-lutely the game has been downgraded since the VGX Trailer (Debut has some utterly horrid scenes, and there was a huge lighting shift even from Debut > VGX), even if some aspects have been improved, on the whole it has been downgraded.
However I still think Sword of Destiny, and all the subsequent 2014 footage, is very much achievable, even if it takes 4K downsampling and everything actually on Max.
I think everyone should be more wary of CDPR in the future, and this is coming from someone who's a huge fan. I think they've still achieved something aesthetically and graphically gorgeous with The Witcher 3, but it's obvious they aren't above PR fluff and rubbish, and the way I see it they really failed to just be honest and down to earth with their fans, which is a big no-no no matter what developer and how much you might love them. I know I'll be approaching Cyberpunk2077 with way more skepticism then I have Witcher 3, and I certainly won't be pre-ordering.
However, I'd say they will have learnt some lessons from Witcher 3, they now know the state of consoles and what they're capable of, and frankly I don't think we will see the same issue when it comes to Cyberpunk, but everyone should definitely still be cautious.
(This is of course disregarding any other aspects of the game and talking purely about graphics. I still think in every other aspect the game is going to be fucking fantastic).
