I don't think that precludes a Solasta sequel at all. It makes perfect sense to me why they might want to trend new ground after spending so long on Solasta. We can still get a sequel in a couple years.
Wasn't saying so, was I? Only confirming that their next game is not going to be a Solasta game.
I agree that creative people don't like to do the same things again and again, or at least want a break from something before they return to it. And in Solasta's case, I also believe TA will want to take some time to evaluate what they do with the DnD license going forward.
