Last week while at SSR in the grandstand, we watched them constructing the treehouses. THese are not rehabs, the old ones are torn down and these new modular units are brought in and slid into place by a big crane. Its pretty cool. We did see the aftermath of what looked to be a modular unit that must have fallen off the crane or truck. The CM at the bus stop said he saw them drop it, but you know those WDW bus drivers......
Never saw any emergancy units so, no one was hurt hopefully, just a big bulldozer thing scooping up shattered lumber and dry wall.

I really wanted to see them, as I'm trying to decide where to book this summer for a few days after our VB stay! They look great, and appear to be coming along nicely! 
I would definitely book them for part of your stay, if you can. The views will all be different so I am not sure if you can put in requests like water view, woods view, etc. They were putting one on the base when we drove by, so the ones nearest the road are being done last. I couldn't grab a picture of those because of fencing and traffic!!
I'm leaning toward booking a treehouse, because how often will you get to stay in something brand new? After seeing your pics, it's almost a done deal in my mind (if I can get a reservation)!!! 
It looks like they are coming along nicely.
