Why talk to the vendors only after the GB is concluded though?
My (relatively uneducated) guess is that adding those two keys would affect the price, so it's likely they're waiting to see if final numbers are high enough that a larger order would offset the price increase for those two keys. Just my guess based off other sets including extra keys based on final numbers after the GB had concluded (Cafe and Metaverse R2 come to mind)
