I am more excited for a title reveal than a trailer drop at this point.
Whilst it would be good to see the trailer in HD, if it's going to be the same trailer or very similar, it's not going to be new to us.
Also, with the trailer, I now have a sensation of what the film is in terms of tone, cinematography, characters etc. Seeing more footage probably won't radically change that.
The title reveal will be exciting though. It will give us a sensation on what this film is all about and will give the film a identity.
Even without seeing Crystal Skull footage.. the Indy 4 title gave us a pretty big clue what for we were in for. Probably TOD was the most vague.. as it did not give away the McGuffin.
