Hey Toast! I was looking at the Saturn Robot KOB page (Team Titanium's KOB entry) and they have a picture of what seems like most of the robots competing in the new This is Fighting Robots show. I say most as I don't see Saturn on there, and a few others for that matter. I don't know if you are already aware of this image but here it is anyway!
I've heard rumblings on Discord that some robots are brought into the proceedings after the initial 48 have already been introduced. We know for a fact that Team Rapid travelled to China around the time of filming, so I believe it.
