Being polite will earn you more replies. Just a little FYI for the future.
The trailer isn't really necessary. After Energon (I'd hardly call that version a trailer, it works for the figure though.) it was realized that the trailer wasn't really a needed component for the figure.
Besides, with the original, how many of us tinkered with the cab part more and put the trailer off to the side after a while?
PowerMaster Optimus Prime was quite a bit different. The trailer fully integrated itself into the cab.
Cybertron Optimus Prime technically didn't have a trailer, since he was a fire truck, but the rear module did become a battle cannon (of sorts), and then a power up attachment that integrated itself into the figure.
Classics Optimus Prime was one of the better figures in the line and while a trailer would've been nice for nostalgia's sake, it wasn't necessary.
Movie Leader Class (and Voyager) Optimus Prime was written in without one, doesn't need one, and kicks all the ass without needing a trailer.
However, Hasbro's not entirely heartless. They did leave a hitch of sort so that if you'd like to add a trailer, you'd be able to with a little bit of work.
I will say this...since the Autobots were clearly left without a home, or a base...Optimus could be given a trailer in the next movie that he could cobble together to create a shoddy (all things considered), yet functional command center of sorts.
It's really sad in a way, but actually fits his character...Prime's the only one left out in the cold. Most heroes are.
Ironhide: Wasn't confirmed, but I don't see why he wouldn't stay with Captain Lennox.
Bumblebee: Does have a home with Sam, he specifically asked to stay with him.
Ratchet: Can go back to the fire department he crashed into, or travel from department to department with no one the wiser.
But Prime...he basically (apparently) drives around aimlessly, watching over the people, ready to strike if needed. At least a command center trailer would give him a reason to pull over and have a shelter of sorts.
I understand why they did it, but Prime got the short end of the stick here.
