Since the rehab came up so suddenly (it's not even listed on MousePlanet this week), I wonder if it was due to an emergency something that needed fixed. IF that is the case, then I imagine they may bring it back up when whatever needs fixed is fixed, and that COULD feasibly be early. I don't know if anyone besides the CMs who work GRR actually know if it might come up early, though (they would have presumably needed to be rescheduled, and would be needed if it comes back up early). Even the maintenance workers (if that is what they're doing) might not know for sure when the work will be completed, or if Disney will reopen the attraction early if it's completed early.
