User blog comment:LoveWaffle/Quicksilver, Scarlet Witch, and Hulkbuster Concept Art for Avengers 2!/@comment-4651179-20140320005158

They all look pretty incredible. I was thinking that maybe a concept art wouldn't confirm a Hulkbuster Armor, but if I'm not mistaken an image was later a BTS image featuring a prop looking like the armor's glove.

PS: I believe what will happen in the spoiler tag, even more as you forgot to tag as spoiler the edit in which you added said info to certain page.
