If this is still in pre-production and you're still working on it, I would ask what specific cameras are being used? Can they handle an embedded timecode channel with Genlock sync? Without that, the frames can drift over time.
Also, what specific audio recorders are being used? You'll need to slave one of them to the wordclock out of the other so that they're precisely in sync with each other, and run off the exact same timecode.
This is more complicated than you might think -- multicamera projects are tough. I've done many projects with 24+ tracks of audio, but only on a single recorder, so there's no complications with sync. I've seen 2 hour concerts stay in sync 100% of the time, even when cameras stopped and re-started, so it can be done if you use really good cameras, all connected in the same way. I think the record for me was a 22-camera concert back in 2008, which took three people working almost 4 months just to sync up all the material... but that was film, done with no timecode on the picture (per se).
I would say a timecode slate on set will be mandatory, since that way everybody can check timecode at any moment.
