If you need that many cameras, I think you need to stick to Vegas for a while. The good news, having used both Vegas and Pr for multi camera editing, is that Pr doesn't crash like I've found Vegas does. I have never, repeat never, had my session end under Pr like what is an all to often occurrence with Vegas. We both know that Vegas continues to have stability problems, quite well documented on their forums, by people like me (G), for years now. Perhaps you've been lucky with your configuration and see less crashes than I did.
My experience with Pr is that while a bit of an odd workflow, (Vegas multi cam is quite a nice fluid workflow), it does work. Now that I've finally got it down, it doesn't seem too difficult (the notion of having to mark sync points is not intuitive, as in Vegas you simply slide the audio into sync, nor this weird idea of nesting mcam timelines). I've not needed Pluraleyes with it yet as syncing via marking points with just a couple of cameras is fine. There are things I'd like to see differently, like actually being able to see the audio waveforms better on the timeline, without constantly messing with the window sizes. (maybe with voice recognition I can just shout, "hey, open that damn window!" whenever I want the audio timeline to expand...but not sure how my wife would take to that...
Since you have so much more camera experience than I do, (I can't imagine using that many cameras!), you might want to play around with it if you have time, and see what you can do. Likely they will remove this limitation of multi camera in some future version,maybe even 6, and the ability to integrate with the rest of Adobe's professional line of tools is worth the effort. There's so much more you can get done with AEs for example, than the lame set of buggy titling tools that comes with Vegas (the NewBlue tools constantly crashed my machine after having had no problems with ProTitler). I had to go back to doing titling by starting a new timeline each time I wanted to do the simplest title beyond basic, render it out and then add it to the main timeline...sheesh. That issue is moot now.
Good luck, and I would go to Adobe's web site and put in a feature request for 32 camera multi camera editing.
I've not tried Avid, if you are needing to get off Vegas, then you might download their trial. But as Conan's editing team mentioned, well, you'll have to listen to it yourself. Enjoy.
