It's amazing how you can get different stories. I was told by an employee at Downtown Disney that they were waiting for stock to sell through before switching over so they weren't sure when exactly the new Wave 2 parts would be available. This was on this past Thursday (June 11th). I was glad that they did still have the Wave 1 parts though as I was able to pick up a bunch of White w/Purple Bodies that I could use with the three new purple colored domes.
Here are some (not so great) pics of the Wave 2 set of domes that I was able to acquire:
R2s (or R2-like domes, I refuse to call an R2 dome an R7)

More R2s and the R3s

R4s & R5s

R6s & R7s

R8s & R9s

You'll notice that there are some droids on the Black w/Silver body from Wave 1, I also had a spare pair of the White w/Black Body from Wave 1 and the new Silver w/Black R9 dome looks great on both of those. The new Black w/Silver & Orange R5 dome is on a Black w/Gold & Silver body which uses the new torso combined with the Black w/Silver legs from Wave 1.
I also picked up some extras of the two R7s and the White w/Cyan R8 so that I could mix and match the bodies among the Wave 2 domes as well as bring in some dome/body combinations with the R7/R8 domes from Wave 1.
After all of the body combo shuffling, here are the resulting Wave 1 w/Wave 2 body parts I now have in my collection as well:

The White w/Yellow R6 on that Orange & White R7/R8 body is for "future expansion" - perhaps there there will be another Orange R7/R8 dome down the line I can put this body to go use with.
The flexibility of the colors this time leaves a lot to be desired. But what I do like most of all is the "set" of purple colored droids since there is now an R2, R3, R4, two R6s and an R9.
All total, I purchased 2x of 54 different droid designs, plus 4x droids with White w/Purple bodies from Wave 1. So this was a very expensive trip

I will try to take better pictures when I have more time...
