I had actually assumed we'd be getting similar costumes to the Transformers performers for the T-60s before that article came out. The Transformers are 12 ft tall and weight almost 100 lbs when T-60s are canonically less than 8ft tall and would hopefully weigh less in execution.
If people can make spot-on lore-accurate Space-Marine armor and walk around cons all day in them, we can get performers in T-60s. lol But i get it. In the confines of a house, swinging around that bulk with whatever props/elements, it would've been a lot for anyone to repeat 500+ times per hour. Glad they flat out announced an animatronic up-front for USH. Probably gonna get a mannequin for UOR
