I've seen accounts of people receiving the new Jawa from EE. I think the order processing is usually a first in, first out kind of deal with a lot of things. I saw some people shared the dates that they ordered this case going back as far as January. I looked at my own order and was surprised to see that was at the end of April. But I think the trend with some TVC collectors is to just order the case blind, regardless of what's in it. I only ordered it when I knew that Maul and Ahsoka were in the case.
It also seems like processing complete case orders does get priority treatment not just from EE, but other online retailers, too. How that works with EE's mint guarantee is curious though, if they're just sending out a case in another box. But from a processing standpoint I could see how etailers could fulfill those whole case orders relatively quickly.
As for individual figures? Again, I think the EE mint guarantee is a complicating factor, and BBTS has a similar kind of guarantee. Putting some of those orders of individual figures together takes time. I was surprised to see my Gaming Greats Purge Trooper and Heavy Battle Droid both shipped on the same day, but in separate boxes. It must just be easier to box up 3 Purge Troopers in one box and 2 Heavy Battle Droids in the other.
