I think the first teaser will be an extended look. With Odin flipping up his eyepatch and glaring menacingly and silently at the screen for 30 seconds, before Thor walks up and gently leads him away. "Dad...no, this way, dad....everything will be all right...."
Then a lightning bolt on a black background with a "THOR: THE DARK WORLD" title card. The end, for at least three more months.
