Michael Bay has posted on his Shoot for the Edit blog thatthe third installment for Transformers 3 is scheduled for a July 1st 2011 release. Previously, Michael Bay had wanted to take a year off before production, and that the release would therefore be in 2012. Looks like that's not going to happen, since today is now the first day of production!

Well its official: We have a great Transformers 3 story. The release date is now July 1st 2011. Not 2012.
Today is Day One. This morning started with an ILM meeting for five hours in San Francisco. Currently I'm flying with writer Ehren Kruger to Rhode Island to talk to Hasbro about new characters.
P.S. Megan Fox, welcome back. I promise no alien robots will harm you in any way during the production of this motion picture. Please consult your Physician when working under my direction because some side effects can occur, such as mild dizziness, intense nausea, suicidal tendencies, depression, minor chest hair growth, random internal hemorrhaging and inability to sleep. As some directors may be hazardous to your health, please consult your Doctor to determine if this is right for you.
Pain and Gain is right after shooting of Trans 3.
Michael
