Hasbro has updated their website with character art showcasing thirteen of the giant robots that are set to appear in this Summer's "Transformers: Age of Extinction". The art is the same used on toy packages and potentially the backgrounds of character profile pages.
The film's director Michael Bay tells EW that though 'Age' is the launch of a new trilogy of "Transformers" films, he's "not necessarily sure that I’m doing [the others]". He also spoke at length about the film's biggest new Transformer character Lockdown:
"Lockdown is an interesting character. He travels the galaxy, he works for somebody else. And he's here for one person, one alien, and then he's out of here. So he doesn't really want to take sides. The cause and balance of the galaxy is kind of messed up when different species play with different species. And that opens up a whole other gigantic world for Transformers.
Lockdown's ship has a lot of meaning that can go into other movies. There's a lot of backstory about that ship that's not laid out here. You're going to see a few things where you're like 'What is that? And what is that?' And you're going to see a couple shots like, 'Wait a minute, who are they?' But we don't answer those questions."
