I assume/hope that Disney has some sort of game plan. My personal bets? Oaken's moves to AFI on the 29th so work can begin on SSI to expand TSMM. Backlot closes on the 27th so work can begin on removing/archiving/relocating anything of importance. When January rolls around and holiday crowds are gone and Osborne Lights are gone and Frozen is gone, then SoA and Premier and LMA and HISTK and Backlot can all be closed off and demolished for a major Pixar expansion. If the Sing Along needs to stay, it can be relocated to the Superstar Theatre (what's the current status of this building? Will it be used for the Comedy Warehouse?)
Again, all speculation. But it seems like Disney is getting ready to do something major in one fell swoop.
