Still no word on if there and when there will be a 2022 event (that I can see), but at the end of November they announced more BotCon labelled merchandise, for fans of the BotCon Brand.
It includes a couple of us$180 jackets... which seems like an expensive extravagant item for a fairly niche audience.
Probably of note is an exclusive (unlicensed) bonus item for some items, of Vok floating heads from Beast Wars, done in cloudy translucent plastic.
(looking on their news page, it was something from the 2021 Robocon event)
