Just seen it. No spoilers.
I will, however, say that as much as the first Matrix could ‘map’ to the Nobilis concept (at least for the combat), the sequel draws the parallels even closer and ties in at much higher meta-levels. One speech in particular (no details) could easily be excerpted and used as a Nobilis side-bar bit of fiction, unedited.
Good movie. Lots of fun ideas to play around with.
