Unless someone has insider info we'll never know. You can't even go off the numbers on the cases since what's counted on them isn't necessary the entire run.
From my experience I would not hold out on these, they will likely never see retail and I'm sure they're the last wave before Force Friday in October. Retailers always wipe thier SW out yearly so this wave will be caught in the void.
It's a low production cost wave too. You got Aphra, BT-1, and 000 mostly being reused parts along with Chopper being light on parts and materials. Honestly Obi-Wan is pretty light on paint too. Ezra has to be the most expensive production wise. While I'm really looking forward to this wave it definitely has the signs of being hard to get in the future. Previous wave was pretty stellar with 100% new sculpts and we got some extra bits they could have skipped on.
I just can't see them making a huge run/second on these characters, only one movie figure in his least iconic look and five others a lot of people may not even know. Usually the more expensive a wave is to produce they'll make more to help balance the cost out. Besides those garabge repack filled waves this is the first time we've really had something like this. I dunno just always seems to be the figures people complain about or don't have as much interest are the ones that Dall through the cracks and become your expensive ones later on. Look at the Shadow Squadron set.
