After watching the interview on game informer, I'm so psyched:
It pretty much all but confirms that Yennefer will figure to some extent in this next game (finally), if the ending of Witcher 2 hadn't all but already made that a certainty.
I just hope they deal with any potential fallout from the Triss-Geralt relationship from the previous two games well as they fold Yennefer back into the story, though I'm also aware that the setting and tone of the Witcher definitely allows for a less than "happy" outcome from re-introducing Yennefer, which could allow the writers to keep Triss-Geralt from being completely tossed aside (especially in light of Yennefer's apparent amnesia).
There was also a part in that interview that talked about Geralt and how in W3, we'd be concentrating on his his connections to family, "keeping in mind that he's sterile", and that really sounds like Ciri will also show up in some way or another (his surrogate daughter for those who haven't read the novels).
The "threat", I'm assuming, isn't really the Nilfgaard invasion. :d
Man, I'm so psyched. I am concerned at the sandboxy change to the game, as it's almost unheard of for sandbox games to have fantastic narratives, but I have faith that CDPR will not let the narrative suffer with the inclusion of the sandbox.
Also, it's different, but I think I like Geralt's grizzled look for W3.
