As I've said numerous times before, it's very unlikely that the two will kiss in this movie. It might happen in the theatrical film, but I wouldn't hold my breath for AtSD. If there was some kind of romantic involvement, it'd be probably be like Isabella admitting her love for Phineas, Phineas acting surprised, blushes, but then says they should just stay friends, to which Isabella agrees.
