From what I have read, the foundation for the Yeti is cracked. They would have to completely dismantle the animatronic monster, re-pour the foundation and put it all back together.
Conservative estimates put the fix at a year to 18 months and millions of dollars. Yeti will never move again....
Granted, I don't know when he started at DAK, nor do I know any of the circumstances he was presented. Still, I think there is a story on why a guy who ran DAK is now going to run Disneyland.
The main challenge will be for DAK to finally get another E-Ticket to take the pressure off of Everest. Once that E-Ticket is built (Pandora) then Everest can go under the knife for a WAYYYYYYYYYY overdue refurb and the Yeti will move again - maybe not the same way he moved before (which was beyond awesome, or "be-awesome"), but his big, beefy arm will swing again, of that you can be sure!
As for the Yeti, I would love to see the beast back in A mode, but it would clearly be an enormous undertaking. Hopefully, Imagineering will come up with a compromise solution.
It is obvious that Iger and CO. realize the WDW Resort needs a little bit of love and they are bringing in the talent to get the job done. Great news!
However, on the Disneyland side of the equation, I am concerned. Michael Colglazier... isn't he the fella who has allowed Everest's Yeti to sit in strobe lit shame for the better part of five years now? The guy should be sent packing, not promoted to run the current flagship park in the US arsenal.
