Well as you know Bane and the League of Shadows gave both Bruce Wayne and Batman the biggest run for his money (& litterly) in The Dark Knight Rises which was the third in the Dark Knight Trilogy. Endless there is Iron Man 4 (I doubt it) I think Iron Man 3 will pretty much be, well to reference one of Stark's many nicknames "The Iron Knight Rises". Do you think the Mandarin will tear Iron Man in and out like Bane did in TDKR? and I don't mean physically technlogically since Whiplash already did that.
I also find it coincidle that in Dark Knight Rises the side-enemies from the first movie came back to stab Batman in the ass during the 3rd movie long after he forgotten them. Well we got the same case in Iron Man 3 since it's going to be 10 rings he's going against. Wow
