Will Loki Show Up in THE AVENGERS 2?

Joss Whendon recently turned in an outline for The Avengers 2, we have no idea what it will involve other than a team of superheroes fighting some villains. He also recently hinted that we might end up seeing a few more heroes in the sequel, but what villains will they be taking on? Will Loki be back for more trouble? Will he even be involved with the sequel? Tom Hiddleson was asked about his involvement in an interview with MSN, and it sounds like he isn't really sure,

I don't know, and that really is the honest answer. I know I've been known for obfuscation in other quarters, but I have no idea, I haven't spoken to Joss. He's definitely doing it. So I suspect not, only because I think that probably the audiences are tired of Loki being the bad guy. Maybe the Avengers need somebody else to fight. But I'd love to be part of it again.

I don't think Loki should be the main villain in the sequel, but I also wouldn't mind him making an appearance. I really like the character, and if there's a place for him in the story that would be cool. I think most of us just assume the main villain in the movie will end up being the Mad Titan Thanos, but there's a possibility he might be the villain in Gaurdians of the Galaxy.

While we're on the subject of future Marvel movies, Samuel L. Jackson is currently making the press rounds for Django Unchained and in an interview with Movies.com he was asked if he would be appearing in Guardians of the Galaxy, to which he replied...

No, Cap 2, then nothing until The Avengers 2, but that's in 2014. Hopefully they'll throw me another Star Wars movie.

The Avengers 2 will be released on May 1st, 2015, and Guardians of the Galaxy is set to be released on August 1st, 2014. Who would you like to see as the main villain in The Avengers 2?
