Congrats on the Dark Droid of the Sith, Kay!
I opened my Master Case this morning. NCS is such a pro. They included a note to let me know they had opened the master case just to include the invoice, but left everything else the way they received it. The display was nicely backed against a large cardboard piece to protect it and is mint off the press.
From Kay's photo above, I opened the Boxes in the same order 1, 2, 3, & 4. Nothing in boxes 1-3, but I pulled the Imperial Officer from Box 4.

Past assortments have had all kinds of random packing I think, but this one was pretty predictable. Here's the layout of the first three boxes:

Here's the layout of the last box with the Imperial chase:

Not sure how the box with the R2 was stacked, but if you open a box with the dignitaries next to each other, you likely do not have the Imperial chase. Now, to work on some rank badges.
Like everyone else, I was very disapointed in the inclusion of R2, but the ability to turn his head is a nice upgrade. Definitely makes for improved poses. Makes me want that Black Astromech a bit more as well. I haven't opened the others yet, but will hopefully have more time to dig in this weekend.
If anyone's interested, I still have a full basic set of figures plus probot for $85. I also have spares of
R2, Leia, Antiles, Tie Pilot, and Vader All gone! Steve - I am working on getting another dignitary for you.
