Lets hope Ron Perlman will be one of the voices you can choose if that is the case..
That suit hanging in the garage looks like an updated version or variant of the T-45D power armour.
Even if there's no character creator, which i wasn't fond of in 3 or NV
One thing about Fallout: the power armors never look the same twice due to upgrades/mods/refits. Even the T-51s from the original games and the Bethesda games look different, which i guess could be explained as later models or something much like they explained why the east and west coast vault doors look different.
