personally i think the stealth 20s will be in the pack with the 3. here is my logic for this prediction.
first off i am assuming that the packs are sticking mostly to OG colors (although the 21 and 22 might have new ones since they arent old at all)
second i am assuming that each pack will have one white shoe and one black shoe. so far that theory has been true for all the jordan packs that we have seen (DMP, BMP, 10/13, etc).
with those two assumptions we can assume the Dunk pack (if that is still coming out) with the 2 and 3 will have to have the black/cement 3s because there was no OG black 2s. so if they want 1 black 1 white shoe in a pack the 3s in that pack have to be black.
because of this the 3s in the 20/3 pack would have to be white, they wudnt have the same colorway of 3s in two packs in the same year. soooo they have to use some white colorway, white/cement or true blues are most likely since fire reds just came out not long ago. so once again, if the 3s are white in the 20/3 pack then the 20s need to be black, which means...Stealths! of course JB doesnt HAVE to stick with OG colors nor do they HAVE to have each pack one white one black, but i think they will. its at least a decent theory, imo.
