00:10 - There's a better look at the fortress, revealed to be the base of operations of Baron Strucker's Hydra cell in Avengers: Age of Ultron Prelude: This Sceptre'd Isle Infinite Comic #1

00:14 - Ultron is wearing a red hood... I mean a crimson cowl.

01:46 - There's a new Iron Man armor.

01:56 - Please tell me somebody else saw that Ultron Sentinel tripping on one of his comrades. It falls in the between Cap and Scarlet Witch.

Also, I think it's worth noting that it appears Hawkeye's sleeved costume won't be his "final costume" as many people expected. He can be seen wearing his Ultimates-inspired suit in the scene I believe is obviously from the final battle. So I think his long-sleeved costume could be just a winter costume, considering he appeared using it in the forest location.
