Ok here me out
Last year Houns dropped somewhat buy surprise and everything was available to obtain the moment it dropped. This year the "Honus" collection will be 2 parts with 2 cards to collect.
There are a few signs that point to this the first being the legends and flashback collection shows 2 players shadows so good indication there will be 2 rewards that release a tiered rewards. The next indication is the clue "The case for" to me this means that it will be work and the main reward you will be chasing for a while and those players that stocked out will be rewarded.
This will be a big and it will be drawn out and it will not be a day 1 card that can be collected
