Not to get anyone's hopes up or anything, but . . . we could have a proper trailer/teaser soon. How soon? How does tomorrow night sound?
Basically, if you had been following the ARG Flynn Lives, you might have been able to score IMAX tickets at five locations (Toronto, NYC, LA, London, and Sydney) and will get to see . . . something. We don't know what it is, but all of these theaters have shows starting within an hour of the scheduled time.
Also,
http://www.flynnlives.com/derez/ needs five codes entered for the next step in the game to happen. Five shows . . . five codes. The last time we had one of these, we got the test footage in HD.
Failing that, there's a 99.9% chance of the trailer going out with Alice In Wonderland (another Disney pic, which will also be in 3d + IMAX) later in the week.
