I'm more concerned about when Rule 34 gets hold of Jack Frost and the Easter Bunny. After trailer #2 you know it's just a matter of time.

Still, it all depends on how they handle him. It's a fairly straightforward meme: He's the new guy joining the established team, which allows him to be the audience vehicle for the introductions, exploration, etc. He could be annoying as hell, and spoil the other characters in the film, or he could be decent. We'll just have to see.
