I don't think you have too much to worry about a Power Rangers revival.
They've been ressusstating that franchise every season with Power Ranger Overdrive, Power Rangers Wild Force, Power Rangers Ghonarea (THAT was an awkward show!), etc. They've beaten that horse more than X-Men writers have done the Jean Grey/Phoenix thing.
Of course, I'm still waiting for a Boy Meets World reunion or maybe a new Gargoyles or Reboot, but I'm sure there's a movie remake of Full House coming any minute.
