Just to play Devil's Advocate, Hot Toys is kinda infamous for revealing or alluding to figures and then never releasing them. It's not a ton, but there's a definite list of things they showed off and just never released, or teams they've left incomplete, so I wouldn't necessarily take them showing off a character as meaning that they'll actually be produced. It doesn't exactly look like it from what I can tell, but they could very well have just taken the old Hot Toys version of that character and dressed them up a bit to look like the new one.
However, I wouldn't be surprised to see that some of these companies may have made the whole team. I'm sure Marvel wanted to keep it secret that certain characters weren't around much, so they probably just sent over all the materials to Hasbro, Sideshow, etc. Especially if it's something that changed a bit later in production, as it seems to have, then I can see them being unaware that Marvel basically nixed one of the characters.
I feel like Bucky and Ghost are givens, like others have said, but not sure on any others. If they did happen to do them all, though, a wave might be the best bet, versus more 2 packs. Ghost seems to be the least favorite of the team as of now; not a knock against her, per se, she just had the least to do and got the least amount of development (I really liked her, though). She, along with Bucky to an extent, were the straight men to the comedic antics of the others. So depending on who you were to pair up with who, the pack may not sell quite as well; and, given that there's more or less 5 characters left to do, it would mean someone not being included. So a wave, with a somewhat important BAF, might be the way to go, or just a normal Spiderverse/NWH-esque wave on cardbacks without BAF parts.
