It seems like they've got most of the signs updated now. We did spot a couple (even one in the parking garage) that still say Downtown Disney, but, I'm sure the sign shop is still furiously working on getting them done and out.
I do have to say...the place is already transforming into much more than we ever imagined it might. For those who've talked of it becoming just another 'lifestyle' mall center...go see it, and if you still feel that way, don't go back. For me, it's nothing like one of those mall centers. It's a fantastic blend (already) of unique shopping, dining, and live entertainment. And, I have to believe the retailers are loving it. Shops were full and the registers were certainly collecting plenty of cash.
