With the profits that are rolling in for CDPR at the moment, I am hoping they will seriously consider creating new content with Triss that is supplementary to what is found in-game. If sales reports are any indication, this game will be a massive monetary success for them with returns of over 100% from the previous installments a year after release. The game has already sold 4 million copies in a two week span of time--double the copies sold for the Witcher 2 some three months after release. Regardless of how many of these sales are from digital copies or discs, the returns are enough to make up for any losses gained when they pushed back the release.
Sales will taper off over the following months, but if they continue to be strong, CDPR could afford to produce more content starring the main cast, especially Triss. I am hoping that their silence is because they, at least, have this option on the table. They have already said they are supporting Wild Hunt for the next 2 years, so this also leaves them the time and resources to make this a reality. The only downside to this would be that the extra content may not be free, because it would require a whole new budget and financial investment. In turn, we may also have to pay for the extra content.
The way I see this playing out is CDPR re-releasing the game as a Enhanced Edition, where all the issues we have addressed on the thread could be answered more thoroughly. There must be developers who spot the narrative issues we are talking about in regards to Triss and co. If their ambition and professionalism in the games they have created is any clue, I would even say they are discussing every possible way they could make the game closer to the vision they had but were constrained in fulfilling.
Of course, like I have said before, we should try to remain skeptical until further notice.
