Third “Transformers” Trailer Debut Dates appears to have got its hands on the promotional schedule for the upcoming Michael Bay sequel, more specifically the dates that new footage from the film is set to premiere.

We’ve already seen that early Moon-set teaser trailer and the recent Superbowl and NASCAR TV Spots. Next up is a longer teaser trailer scheduled to hit March 25th, likely with “Sucker Punch”. Two key TV spots will then premiere on the Reelz Channel on April 3rd, MTV on April 21st.

The big full-length trailer is scheduled for May 5th 2011, almost certainly attached to all copies of “Thor”. Another TV spot will then premiere on Nick on June 13th.
