Will THOR: THE DARK WORLD include all of the Nine Realms?

First off, I would like to say that Marvel and Kevin Feige are full of surprises, so if you find that you see Elves, Giants, Demons and Dwarves in the Thor sequel, you would know why.
Now that we have that out of the way, according to resources we may see the Nine Realms in Thor: The Dark World!

Previous 'Scoops' had confirmed that the Dark Elves will play a big part in the sequel, with Christopher Eccleston and Adewale Akinnuoye Agbaje playing the parts of Dark Elves: Malekith and Kurse, but now we have confirmation of the World Tree also known as 'Yggdrasil' being involved

Marvel Studios released a piece of artwork which may prove that the Realms may have a big part in the story:

Thor has many villains in these realms and for The God of Thunder to battle them all, would be battles worth at least four movies, so how will they have them in the movie?

What do you think?

Will they all be included in the movie, cameos maybe?
