Re: Next Armors
I think the picture posted by DrDoom is a design that feels believable in the MCU. It doesn't strike me as particularly beyond anything they've shown in the movies so far and seems to fit the style of previous armours. We've already had large suits in the IM movies themselves with Iron Monger and arguably the drones (which weren't meant to be drones) and Whiplash's armour was quite large itself.
And that's not counting the stuff in Avengers.
