Just at USH for a few hours on Wednesday (1/9/13). SO much behind walls in the upper lot, more than I would have expected. The Wild West arena is still completely surrounded with the "new" construction walls, and there's heavy equipment back there (didn't get more of a view than the backhoe shovel over a wall). T2's continuous in walls themed to the areas they're wandering through - English storefronts on that side, French the other. This DOES give a fairly amusing shot of the "modern future" CyberGrill building/signage directly over a wall painted as a patisserie, which I count as bonus.
Construction is apparent in the backlot as well. Aside from the parking lot full of (and kinda sad general destruction of the area used for) Grinchmas, the tour also routed around a construction staging area full of pipes up in the rear end of the tour.
I'm a little alarmed at HOW MUCH of the upper lot's in flux. I'd seen and read the reports, but this is akin to the heaviest stages of DCA's remake - you really can't get away from something under construction in the upper lot right now.
It'll be worth it though
