The make or break for me is how dopey/sappy/family-friendly Revolution is. Broadcast has a hard time being as tough-minded as cable (which they could do, even without extreme violence or swearing, so it's not all the FCC's fault). They need to go for more of the sensibility of The Walking Dead and stay far away from Terra Nova's stultifying tone.
Revolution's timeslot will probably be taken over midseason by Smash. That will sure be a shock to the audience!
The straight guys will bail in a hurry...
If NBC had another action/adventure series to slot in their instead, it would help hang onto the audience for that timeslot. Say, Crossbones or Hannibal. But the post-Voice slot makes more sense for Smash than anything else.
