Okay, well after watching those episodes I'm kind of surprised none of the stuff you posted popped up.
However I will say I loved the fantastic four cameos and how Thor has a big influance on the second half of the season. The episodes with Ultron are AWESOME and they really show how badass and as big as a threat he is and the final episodes were awesome and I LOOOOOOVED the new armor tony got which was obviously the Thor Buster armor. :3 Kind of surprised the destroyer armor didn't make an appearance yet but oh well it was pretty good either way.
Now as for the pictures you've posted, MAN I look forward to the next season even more. Dr. Doom, Ronan the accuser, and the vision. Can't wait for the future episodes where the squadron supreme is suppose to be in or atleast nighthawk is suppose to be in, which he's voiced by Kevin Conroy aka Batman the animated series Batman.
