Problem with that, is it gives the impression to the player that Triss is still a valid romance option and it would be continuing from the previous games. A lot of Triss fans from what i saw were worried that bringing Yen back would mean that Triss is no longer an option and that scene sort of gave them hope knowing that they could purchase this game with some level of confidence in regards to the romance options.......needless to say what we got in the end.....well i think it has already been stated too many times lol.
Can't find fault in anything you say...it very well could have been this 'teaser' that caused the change of opinion;
"...so, wait...when does Triss enter the game?"
"Well, she is in for this little bit and then Geralt says good bye at the docks and she's gone...from the game..."
"What?"
"Ummm, well...this is a story about Geralt finding Yen and together trying to save Ciri...where would another...I mean, how could Triss...its...if you turn to page 187..."
"SO, we spend 8 years building up Triss as the main interest in Geralt's life...she stands by him through ALL the shitstorms and..."
"Well, I guess we could bring her back for the fight in KM?"
"Thats a good start..."
"We could add her back as a love interest?"
"Nice...you have six months til it goes Gold...thanks and make it happen!"
(thuds) thats the sound of the directors of the project passing out...
