I think its fine. Literally the most powerful beings in the world of the witcher are the sorceresses who are obviously all women. I think the female cast is treated well even Kiera who's decision to wear a incredibly revealing outfit is pretty well suited to her personality as she is incredibly vain person who values classical beauty very highly. Its also a tool she uses very frequently to use her wiles to get what she wants. She does just this to Geralt whom she seduces and then puts asleep with a spell so she can get the research papers from the isle and worm her way back into a potential life of luxury again. Like if you want to argue that Witcher 1 was sexist well you'd have more of a point as you literally god collectible cards with naked women as souvenirs of your sexual conquests. I think Witcher 2 and to a greater extent Witcher 3 paints its female characters especially the main cast in a much better light.
The 360 only had like 512MB of ram and still pulled off some damn impressive things. The fact that these consoles on a hardware level are behind PC's doesn't matter because the way the hardware is being used is way different. They can squeeze way more out of way less. I don't think we've hit the ceiling just yet with these things. I think the true showing of what the Ps4 can REALLY do is going to be when you see Uncharted 4 drop.
