This isn't new. Layton apparently hasn't updated his site in quite a long time. That concept is likely the art concept drawing of June.
There is a redesign coming that is slated for August, so I think it is June's thats still up.
Not a fan of the newer concept, though I like the original one. I think the infatuation needs to stop with the extremis armor by Marvel. It seems like every armor now has to be influenced in some way by the style of the current armor. It's making things boring.
