Iron Man 2 had finished filming and entered post-production back in July, so it was expected Marvel would present a trailer in the near future. Earlier today director Jon Favreau retweeted a message from someone on Twitter, and it hinted that we could see the first trailer with Sherlock Holmes on December 25th.

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