considering that the first 56 figures were all new sculpts
Just wanted to nitpick a little with this, Jesse.

-The Super Battle Droid is a slightly modified version of the 2002 Saga Deluxe Yoda with Super Battle Droid
-The Battle Droid is a repaint of the 2002 Saga Battle Droid
The Destroyer Droid is a slightly repainted (with new missles) version of the 2002 Saga Destroyer Droid
-R2-D2 (#48) is a modified version of the 2002 Saga R2-D2 (Coruscant Sentry) which was a modified version of the 1997 POTF2 Power F/X R2-D2
So, technically, we got 52 totally new figures this year in the basic line (which is still a whole hell of a lot to me).

The last waves are always the toughest to find it seems, and if people don't want them...they don't have to worry about them. Although I do hope that everyone that is looking for them is able to pick up what they want
This is what worries me (this being the last wave) the most about the final 12 at this point. While some of them are just plain awful to look at and make me wonder what in the world Hasbro was drinking/smoking/inhaling (namely the Wookiee Warriors and the Neimoidian Warrior), some of them (namely everything that is derived from Mr. Fett's DNA) are really nice, and if a lot of people miss out on them, I can see a big swell in anger toward Hasbro if they aren't reshipped again on TSC cards (themes or not, you just don't release new Clones at the end of a line and then never reship them).
If Hasbro honestly wants to avoid a problem with this, they need to double the production on each and every Clone in the last 12. That way, retail gets their share, and Hasbro can do a "2 per customer" thing at HasbroToyShop.com to prove the site isn't completely useless (even though I know some will have a problem with the 2 per idea) and to make sure that everyone who wants one will be able to get one (or two as the case may be).
I think one of the most logical moves they could have made is to not split them up into Collection 1 and 2, and instead release the final 12 as a one per case assortment and make enough cases available to EE or somewhere else so collectors could buy their case, get one of every figure, and be done with it, and if they wanted more, there would still be a large number that shipped to retail.
Something else I noticed is that the first 7 of the "final 12" are all Collection 1 figures, and only 5 are Collection 2. There are 12 figures in a case, and it doesn't take a genius to figure out that:
-If all 7 Collection 1 figures are released in a case there are going to be, at least, two figures that are shortpacked.
-If all 5 Collection 2 figures are released in a case, two of those figures will be 3 per case, at least.
So, if they had to do their 2 Collection assortment thing they have been doing for years, they could make things a lot easier and move one of those Collection 1 figures (why the hell is Cat Miin C1 anyway?) over to C2, and have each figure shipped in an equal amount: 2 per case. Then again, I really don't think that the Neimoidian Warrior repaint should be packed at anything above 0 per case, but at the most 1 per case.
And given the indication that the repaints of the Clone Commander, Pilot, and the 501st Clone are going to be one per case in this next Collection 1 assortment, I'm still of the belief that this is going to be one massive headache when the figures start shipping. All I can say is that if I see extras of any of those three figures, I'll be picking them up for people here.
