Thanks for including the full-res images!! Wish I could give you 2 likes.
Wow, based on that first image, I didn't realize how much more space they're clearing for the expansion.. it looks like it's going all the way up to S Studio Drive, and if I remember correctly they're going to be clearing more land south of S Studio Drive for a new entrance? maybe more parking?
Red area is what we see being demo'd now, you can see the previous green area in the bottom left corner now cleared.

This also gives me much more hope for the new fireworks launch location. I think the worst decision was moving it so far away (yes I know, it closed down the back half of the park).. but once SWL opens, we'll be able to get a much closer view.. I'll imagine they'll have some type of backdrop in SWL that will serve as the central focus with the fireworks going off behind whatever it is (similar to the castle in MK).
