...looks about as good as the last one, which is to say pretty damn good.
Not much "new" on display, but at least better looks at stuff that only flew by quickly in the previous trailer. Of particular note, though: "The Mandarin" does, indeed, seem to be called simply "The Mandarin" - which means that the proud Marvel Studios tradition of straight-up lying about this stuff is alive and well. I'm liking that they seem to be doubling-down on the "Ten Rings" as Al Qaeda angle from the first movie, with Mandarin looking more and more like a slightly more theatrical, pan-Asian Bin Laden with each new
If I had to guess, I'd imagine the "Iron Army" bit at the end involves remotely-operated "empty" suits; which sounds both like a fun idea and an interesting workaround to the issue of "will people be satisfied with 'only' Iron Man after seeing him with The Avengers?" The big lumpy one at the very end is, obviously, supposed to make you think of The Hulk - but I can't tell if it's supposed to be specifically the "Hulkbuster" armor from the comics - which everyone wants to see at some point. (Sidebar: Given that War Machine is already wearing Captain America/Iron Patriot colors, it'd be a fun detail if some or all of these other suits are specifically designed to be "supplemental Avengers.")
Also: The shot of Pepper Potts in some kind of harness (and is that her in the sports-bra at 2:01?) returns, though this time it looks like she's actually in the same aparatus we see Guy Pierce's character strapping a bunch of burly henchmen into elsewhere. "Extremis," the storyline this is partially based on, involved turning people into bio-weapons, so take from that what you will.
ALSO: Yes, I've heard all the same gossip about the ending as everybody else has. I dunno whether to buy it or not, but I'm not seeing many indicators of it here.
