Transformers questions by newbies, and not-so-newbies

[Paulbot]

Is Piranacon/King Poseidon the only instance of the US and JP versions of the same combiner having different canonical positions for the limb-bots in the combiner?

I think there's some others but I might be thinking about how some toy packaging/instructions have different arrangements to the cartoon model.

Updated my collection list and got stuck.... What are we calling the "Selects" ranges?

The hasbro based ones fit nicely into the current lines...

Richochet, Red Swoop = PotP
Powerdashers, Hot Shot, Smokescreen etc = Seige

But what about Star Convoy, Seacons, and one day Super Megatron??? It was the Seacons that tripped me up... Are they PotP? Starconvoy could be, but Turtler doesn't have a core....

I'm consider the Selects as it's own line (like good old Transformers Universe - from wow nearly 20 years ago?!) but would treat all of the releases so far as "Generations" (CHUG) toys and put the Seacons next to other CW/United/POTP figures for instance on a shelf.
