We got our first bit of news about possible added romance in the expansion. Leave it to Kotaku to ask the REAL questions we want answered about Phantom Liberty. It seems there is SOMETHING added, romance wise, according to CDPR developers when asked by Kotaku but were vague as not to spoil anything. I know site friends LJR, Llivia, Zwei and Skelly will be glad to hear this. Simps all of them!

The developers were hesitant to get into specifics to avoid spoilers, but Sasko compared the DLC’s new romancing to The Witcher 3’s Hearts of Stone expansion, which unlocked additional dialogue with characters like Yennefer after it was completed.
“So we have included some connections in places where it made sense between the main game and expansion, but I don’t wanna go into detail,” Sasko said. “We tried to make it good. This is always our idea, you know, to just like, take care of the players that [enjoy those relationships].”
