Plans for the rehab were finally filed with the SFWMD yesterday. Since these documents are considered public record, I hope there's no issue with posting images from them here.
Here's the project description from the Geotech. report:

Looks like they'll be adding a total of 26 "lodging buildings" facing Bay Lake, as expected. However, unlike the Poly bungalows, these won't be built over the water, and it looks like only about half of them will have any decent view of the MK fireworks. It also appears they'll be upgrading/expanding the pool adjacent to the Villas building, and adding the new recreation buildings mentioned in the project description to that area, as well as what I assume to be a new restaurant building near the boat dock.
