From Wahlberg's latest interview, Mark Wahlberg on his new film 'Broken City,' bodybuilding, and 'Transformers 4' (Examiner, 17/01/2013):

Will you have to put more weight on for “Transformers 4”?

Wahlberg: Well I took a month off – I just started working out, I’m in my 4th week now – hopefully we’ll do “Avon Man” before “Transformers,” which is this comedy we have at Fox that we’ve been developing; it’s kind of like my first romantic comedy.

Can you tell us anything about “Transformers 4” or “Ted 2”?

Wahlberg: I could tell you that we’re doing “Transformers” starting at the end of May, and then “Ted” in September. You know I can’t give you too many story points or Michael will not be happy. But I can tell you that I’m very excited, obviously I had a great working relationship with Michael on “Pain and Gain”.


And recently, Mark Wahlberg says COMPLETE REBOOT when he appeared on Jay Leno's Tonight Show (16 January 2013):

"We’re doing a complete reboot of the Transformers. I did a movie with Michael Bay called Pain and Gain, which comes out in April. And we had an amazing time together and really hit it off, and he said ‘Hey, you want to do this other little movie I’m doing?’ Because that was a little movie, and I said ‘Yeah, I like doing little movies.' And he said Transformers. Whoa! You know what, we had such a great experience, I’m in."

Unfortunately, the actual video link (from the NBC site) won't work for us here in Australia.

I don't think he actually meant it in the sense of a complete story reboot...
