From the trailers it looks like there is more going on that just Lockdown and human built robots. So far Hasbro and Paramount have been pretty good at not spoiling what else might be in the film.

We've seen Vehicons in Prime so it doesn't seem like you'd need Dinobots just to take down Vehicons. Lockdown seems a bit of the Boba Fett type where they could add something cool to a film but not the main villain sort of character. Galvatron, a ton of fan speculation with what they have planned there. So it would seem like someone is showing up with those ships.

 

The main villain is totally going to be Kremzeek.

 

The majority thinks it's unicron as do I. But bay might go left field. It could be a cybertronian coalition of both factions coming to reclaim their technology, interrogate optimus for his abandonment and so forth and enforce the law of tyrest accord. Lol .......on and on.......and....

 

Definitely possible I mean the decepticons/lockdown need something to counter the dinobots

 

Exactly what I was thinking,those Dinobots look like they are gonna mess shit up haha.

 

wolfgang.

only thought that comes to mind

 

I feel like there may be something bigger, I just don't know right now.

 

I still know what it is... you guys just don't get it

 

Well what do you think it is?

 

its you-know-who, that's what.
