I know we still have 6 weeks or so until Moon Knight even begins, so it should come as little surprise we didn't get even a teaser for this tonight, but I was holding out hope still. The way Disney+ seems to like to market things is so that they are just starting to market the next new big thing after the current big new thing is underway. A few examples:
Moon Knight - first proper trailer came out on January 17th, after three episodes (or 43%) of The Book of Boba Fett had passed.
Falcon and the Winter Soldier - first proper trailer came out on February 7th, 2021, which was after it's five episodes (or 55%) of WandaVision.
What If...? - first proper trailer came out July 8th, 2021, which was after five episodes (83%) of Loki and also the day before Black Widow premiered.
Hawkeye/The Book of Boba Fett - first proper trailer came out October 28th, 2021/November 1st, 2021, which was three weeks after What If...'s last episode, but 7 days before Eternals released. Disney+ Day is on November 12th, so they wanted both of these released.
What I think is most likely to happen is that a teaser comes out around mid-April (halfway through Moon Knight), but the full trailer is held until May 4th, which is two days before Multiverse of Madness releases, which is the Disney marketing machine in full motion, much like how What If...? was released right before Black Widow and Hawkeye/TBoBF trailers were released shortly before Eternals.
So I think we've potentially got quite awhile still until we see a any footage for this thing.
