If it does turn out to be true I will definitely be disappointed.
I honestly can't think of a figure for Commander Class that would fit into Kingdom. I mean there could be some beast related figures that may, may, work. It just seems to be the theme that is making me wonder. So far the 2 Commander class figures have fit into Siege and Earthrise, while also be big G1 toys. So what fits into Kingdom that is G1 or BW?
Is Rodimus Prime really big enough? Or as stated earlier, will Commander class become a Leader with a ton of accessories?
Studio series 86 hotrod (kingdom is another line altogether) is physically a deluxe class figure but is being sold as a voyager due to the accessories he comes with but those accessories don't justify the $10-$15 (depending on where you buy it) markup so it's just hasbro ripping us off again.
