Thanks to Nico for the heads up.
My wife and I just returned from Hawaii and, while hiking in the Manoa rainforest we ate at the restaurant (the scene with Miles and the body in the kitchen last season was his kitchen as well as parts of the Orchid Station set) where some of the LOST sets are constructed - the owner was an awesome guy and when we noticed the polar bear cages outside he said they had been put back up 2 weeks ago and the cast was coming back to shoot this Thursday
Apparently Sawyer returns to the other island to visit the bear cages at some point coming up
Hope that helps!
