Has anyone seen anything about the Hoya Sq100 filter system? Hoya is getting into the 100mm square filter market (I'm actually surprised they weren't already), and this seems like a nice system with accommodation for a polarizer. The announcement says "Sales will commence on March 15, 2022", but I haven't seen it for sale anywhere.
