The villain in Avengers 2 is Ultron, not Thanos (the movie is called Age of Ultron).
"The sequel is set a year after Man of Steel, and the world is still getting used to having this powerful god on the planet who isn't fully trusted by everybody. Batman certainly doesn't trust Superman. Superman doesn't trust Batman; either of which causes the two to clash when they initially meet. They do however pair up to defeat the villains (not 100% confirmed who the villains are). COULD be Luthor and Joker, but only a select few really know that. Luthor is definitely in the sequel and he doesn't like Superman, believing him a threat to the planet."
I'd rather they use someone like Hush or Deadshot (Lex is fine though).
I've wanted to see Hush in a movie ever since I read Paul Dini's Heart of Hush story (it convinced me that Hush was a great villain). Deadshot is just cool. Riddler would be interesting as an actual mastermind/genius (not Jim Carrey), maybe someone like Damien Lewis.

That could work. Lex, Slade, and Metallo (three villains just like the report says, I like it). Can we please get Manu Bennett to play Slade though, he is AWESOME on Arrow?
I want Metallo in the film, but DO NOT tie him to the Wayne's murder. Batman works better when it was a random thug that killed the Wayne's because it shows that Gotham is so corrupt and crime-ridden that a common criminal could kill it's most prominent citizens, and that is why Batman is needed. Having a supervillain kill them negates that (I hated when Burton did it as well). I agree with the rest of your post though.
