Would have been nice to get a Rebels 4-pack - Imperial Chopper repaint with maybe R2-D2, R3-A3 (from Sato's group), and BG-18 (from the Mon Cal who made the B-Wing).
But then someone at Disney would have had to give Rebels more than 5 minutes of attention over the past 4 years. 
Give it time. It took them 19 months to get a Droid Factory BB-8 out and they just released the "standard" Chopper at SWCO this past April. Not to mention the fact that we also got a Clone Wars 4-pack at SWCO too.
This has been one of the more ambitious years for Droid Factory:
- R5-013/R2-C2/R5-S9/R5-P8 - Clone Wars 4-pack (SWCO)
- C1-10P "CHOPPER" (SWCO)
- R2-D2 / C-3PO 40th Anniversary 2-pack (SWCO)
- R-3D0 (SWCO)
- R5-D23 Exclusive
- R3-B0017
- BB-8
- BB-8/2BB-2/BB-4/BB-9E - The Last Jedi 4-pack
- R4-X2/Y5-X2 - Force Friday II/The Last Jedi 2-pack
- R3-H17
- 21 New Protocol Droid Heads along with the corresponding arms, legs & torsos
Before 2017, there are had only been 7 carded figures, two box sets and the two waves of Astromechs all spread out from 2012 through 2016!
To put that in perspective, once R3-H17 is released that will mean SIX carded Droid Factory figures for 2017, plus two 2-packs (which are new in 2017) and two 4-pack box sets (of which we got one in 2015 and one 2016).
