It seems that director Jon Favreau may have dropped a subtle hint about when to expect a trailer for his upcoming superhero sequel. Favreau retweeted a question about a trailer for Iron Man 2.

RT @Ann_Howard: @Jon_Favreau PLEASE tell us the trailer is coming soon - w/Sherlock Holmes, perhaps??

While Favreau didn't respond to the fan's tweet, the fact that he retweeted it could be a significant hint. It does also make sense that the Iron Man 2 trailer would be attached to Sherlock Holmes, since they both star Robert Downey Jr.
