When I went to see ROTF last summer with my younger brother and sister, I was really shocked at all the dog humping, leg humping, pot brownies, Alice sex, etc, and the robots cussing. Now, let's acknowledge that probably a half to a third of the audience that gives the films 700 million+ dollars has been kids. And with ROTF, lets be honest - mothers were probably PO at all the crap in the film their kids had to sit through. Mothers probably won't bring their kids back to TF3, remembering all the crap from ROTF. Without kids - if this indeed happens - Bay loses about half his audience and $$$$. Which could bring TF3's total to half of ROTF. This a "worst" case scenario, but its not unlikely. To sum it all up - with the crap in ROTF, TF3 will not make as much money as ROTF.
