As Swen told a lot already though, the theme and DOS:2 in general will be way more "mature".
I certainly look forward to a more mature sequel. I've said before that I felt some of the humour in D:OS was too juvenile for my taste (eg, the scene of teleporting into the woman's bathroom).
But I don't believe that maturity is incompatible with humour. I remember being enthralled with Prince of Persia: The Sands of Time, which had some interesting themes and plenty of fun moments. But the sequel decided to be
darker and edgier and I struggled to find anything I liked about it.
We could probably argue for days about what is or isn't juvenile. But I hope I've made my point.
