Anyone seen a nice, comprehensive list of the new parts/colors. I can't really tell what all is new from that little pic further back in this thread... I'd like to know whats out there before I go hassling Paul with requests. 
I believe this is the list - like Jesse said, when you combine "Wave 2" and "Wave 3" you get pretty much the same number of parts as Wave 1 from three years ago...

In Wave 1 there were 25 Domes (5 R2, 2 R3, 3 R4, 3 R5, 3 R6, 3 R7, 3 R8 and 3 R9), so the total number of domes is the same, but the break-down of droid type is different. Essentially there is one less R6, R7, R8 and R9 then there was last time and there are four more R2 domes then last time.
For the other parts...
Trunks1. White R2/R3/R4/R5/R6/R9 with Blue
2. White R2/R3/R4/R5/R6/R9 with Red
3. White R2/R3/R4/R5/R6/R9 with Green
4. White R2/R3/R4/R5/R6/R9 with Yellow
5. White R2/R3/R4/R5/R6/R9 with Purple
6. White R2/R3/R4/R5/R6/R9 with Black
7. Black R2/R3/R4/R5/R6/R9
8. Red R2/R3/R4/R5/R6/R9
9. Green R2/R3/R4/R5/R6/R9
10. Blue R2/R3/R4/R5/R6/R9
11. White R7/R8 with Black
12. White R7/R8 with Blue
13. White R7/R8 with Yellow
So there is 1 more trunk in Waves 2/3.
There were ten different leg color designs that matched trunk designs 1-10 listed above, but since there were different "left" and "right"legs there were 20 different leg pieces to collect. In Waves 2/3, there are two additional color designs, but the good thing is that you get two of each of leg part every time you get a droid with matching left and right legs, so that's a "plus". (especially in my case where I'm trying to make sure that I have at least two of every part in a "set")
For middle legs, in Wave 1 there were five - White, Black, Red, Blue & Green; and for hats there were eight total: Red, Black, Blue & Green Mouse Ears, Indy Fedora, Jack Sparrow Pirate Hat, Goofy Hat & Yoda Baseball Cap.
So here are the totals:
Wave 1: 25 Domes 13 Trunks 20 Left & Right Legs 5 Middle Legs 8 Hats Total: 71 Parts | | Waves 2/3: 25 Domes 14 Trunks 12 Left & Right Legs 7 Middle Legs 7 Hats Total: 65 Parts |
I hope this helps. I'm still almost a month away from being at WDW. I get in on a Thursday and will be hitting Downtown Disney that day. My hope is that the parts will be there too and I will be able to get a good chunk of what I need. My parents will be in tow, so I've read that they are limiting you to 25 droids (I guess their thinking is that you are gonna want one of each dome) - so if (and that's a big if) they have all 65 parts available, I'll be able to make a set of 2x of each of 25 different droid designs. I am still on the fence on whether or not I want to get two different designs with each dome like I did with Wave 1 (my Wave 1 collection has 56 different droid designs, and I have 2 of each of those designs).
I also have pairings that aren't 100% ideal - such as the White w/Purple R4 Dome on an all Black body. I'd love to identify a dome in the new Wave 2/3 set that would look good on a Wave 1 Black w/Silver body (for example that Silver w/Black R9 Dome) and then buy that dome on the all Purple body of Wave 3 and do a swap. Don't know how feasible that would be though on this trip...
