Shows the diecast content - the announcer says it's heavy, but it doesn't look like it has as much as KoB. It looks like the connections will be pretty solid. Yellow and Blue Lion appear to have midsection joints, which should be good for posing Voltron - they also have fold out heelspurs for more balance. Lion heads look to have much more movement too

Btw the last 20 minutes of this vid has some Super Ginrai and Diaclone prototype footage too
