here is the link to the architects's digital models. In at least one you can see the space in theatre mode and to my eye it appears reasonably raked in the stadium seating vein. I can imagine it feeling pretty cavernous but my other experience with sitting in spaces designed by DS+R (and Rockwell) makes me think they are sensitive to everything. We shall see of course.
PS It's in the 2nd video that you get the best impression, including the cheap seats :-(
