While the (legit?) new lines are simply just lines for the sorceress of choice and don't change canon, a couple things bother me and I'm just throwing them out there, even if my thoughts aren't 100% about only Yennefer. (Within Opinion Land):
1) I don't understand why Yennefer is still the center of the Triss/Geralt romance in the new lines like there's nothing to talk about. How romantic, fulfilling, and so worth the wait for CDPR to prove and show how special Triss/Geralt is? If anything, they're still putting more importance on Yennefer and her history with Geralt. Absolutely nothing new and special that would make me, as a Yennefer/Geralt fan, want to choose Triss in my playthroughs.
2) I find it hard to support the new romance lines simply because they turn Geralt into a liar. IF the "always" comment refers to the events in the books as well, Geralt would be saying Triss's name in bed with nearly every woman, including with Yennefer. But he doesn't. It's Yennefer's name and it always has been. And before the "omg but the wish!!" crowd goes crazy, even after the wish is undone, there is no insane revelation that his whole romantic life has been a lie and he was nothing but a victim puppet with a whole fake romantic persona besides saying the magic was gone (if you choose it) and that's not indicative of a victim who is finally free of nothing short of torture. The wish never stopped him from having sex with anyone he wanted to or even loving anyone (Fringilla, for example, whom he says he loves in his own way which could even be taken in a more personal sense). If the wish couldn't even do that, it wouldn't stop Geralt from saying Triss's name if she is who he loved "always". Just to repeat, Geralt's wish with Yennefer was so powerful that Yennefer's slave Geralt couldn't say Triss's name in bed, yet had sex with all the women he wanted and told someone other than Yennefer that he loved them. You'd think that with all the personal thoughts we've been given by Geralt throughout the books, he'd say much more about his true love Triss considering, as proven, this is outside the power of the wish? At least have the sense to make him say something that suits both game canon and book canon (as best as you can) if it's going to be taken seriously. The "always" line is either Geralt's pillow talk or a complete lazy joke by the devs/whoever wrote it.
If I were a part of TT, I'd be bothered that they didn't make my choice valid within both the canon of the games AND books, and would want something to differentiate how special my chosen couple is instead of being reminded of Geralt's time with Yennefer yet again. Not to mention that an all encompassing "always" should even get a huge eyeroll from Triss herself. She shouldn't be that gullible and I wouldn't expect her to be because it only disrespects them both and how far all three of them have come. Acknowledge the past and move on from it, don't go back and say "I was like this all along!" and expect everyone to believe it. For those who do love and respect the new lines, enjoy them. That's why the extra time was taken to put them there. CDPR values us and their games enough for that and I'm thankful.
Opinions though. If the developers want us to disregard the books completely, at least tell us instead of giving us The World of The Witcher book which clearly explains the importance of them being the past of these great characters. Overwriting an important aspect for the sake of the fans literally turns things into fan fiction.
