it already happened
as of this patch 9 the main character should be auto selected at the end of combat or when a talk happens... the small issue is that change they made doesn't work
Hasn't happened yet at least not for me, I finished a fight earlier (The harpy's, and the kid triggered dialogue with my part member).
And hasn't the the game always defaulted to the PC after combat? If no, that is a really good change to the game.
