Is there a reason that Devon Aoki isn't in this one?

I am curious about what they're shooting it on, the first one had a video-y look that was a little more apparent when they were against greenscreen (and the CGI was rather soft), it's been a few years, I don't know if RR rocks RED yet but I imagine between that and the more "solid" looking CGI we get these days we'll have a more realistic feeling movie (although if they actually went OUTSIDE to some kind of city to shoot a couple angles, that would be good too...)
