What I think is the new typical situation with BB games from LRG is that they will not list them until all versions of the game LRG has sold have shipped or are at least in the shipping cue unless they have a specific date in the contract that allows BB to sell earlier. The idea, as I've gathered, is LRG wants to ensure it's customers get the game first. So right now the issue isn't the standard edition it's the Classic Edition which ships sometime Q2 2022. I wouldn't expect BB to list until after the Classic Edition is at minimum in assembly and then they will use a release date sometime after what LRG estimates it'll be for those CE's to ship.
Adding to this, if BB did order standard edition copies then they had to be manufactured with all of the other copies. So, they are likely under contract for them already and it's just a matter of time since LRG wouldn't have printed the order without it being confirmed and LRG isn't reprinting the game for the BB release later. Ms. Splosion Man was only a standard edition (no CE). It makes sense that this one could be easily cancelled or that the listing would reflect the situation better. It's also likely that BB doesn't pay until the bulk purchase is ready to be shipped. So the delay due to the CE, likely makes this easier on BB since they aren't out any money. That is, if BB is even paying up front for these games. It's possible there is a more vendor type situation going on here where LRG gets paid after the games are sold. It's hard to tell exactly without inside information, but I think with any of these games with a CE attached, unless the listing is updated after the standards have shipped to delete the BB message... everything is 100% going to BB due to being under contract.
