Am I the only one who hopes that they take a cue from Ultimate Thor and drop the corny Shakespearean dialect that Thor uses? I mean I know a lot of people think it's "iconic" and makes him sound "god-like," but I've always wondered-- what on earth does Shakespearean English have to do with ancient Norse mythology? They're two completely different cultures from two completely different time periods, and the accent has always been one of those silly things that people just sort of seem to accept about a character.
Above all else though, I don't think the audience would be able to take the character seriously if he's talking with "thee's" and "thou's." When I saw the Hulk vs. Thor DTV, every time Thor opened his mouth I couldn't help but snicker a little just because his dialogue sounds so corny when someone is actually reading it. If the audience is going to take Thor seriously, I think that their best option would be to make him speak in plain English.
