Is This Megatron in Transformers: Age of Extinction?

Seen in the Super Bowl TV Spot for Transformers: Age of Extinction is a robot who transforms a part of itself into a (long) barreled cannon, and the Decepticon's MEGATRON automatically pops into mind, reminiscent of his Generation-1 heritage transforming into hand-held pistol? This is purely hyperbole and speculation on my part, and appeals to me somewhat, compared to the alien spaceship-monstrosity from the first three movies - which I actually did like as well, truth be told, but was so far away from the "source", ya know?

Dinobots in Transformers: Age of Extinction

Remembering the denials read in multiple online venues from filmmakers about the involvement of DINOBOTS in the latest incarnation of the Transformers movie, everything has since been forgotten when we see flying creatures and roaring dinosaurs in the Super Bowl TV Spot for Transformers: Age of Extinction - which everyone (including myself) take to be "Grimlock" - which nobody has admitted otherwise though!

Nevertheless, let us revel in the visual of Optimus Prime riding the "Dinobot", brandishing a sword in one hand, drenched in 80s-90s American cartoon memories! LOL

Transformers: Age of Extinction Big Game / #SuperBowl Spot

Debuting at the Sunday Super Bowl is first ever footage of Muchale Bay's 4th film in the franchise; "Transformers: Age of Extinction"!

YES, there be Dinbots! And seeing Optimus ride Grimlock might well be something to leave a wonderous mark on the pysche of impressionable minds of fanboys and fangirls -both new and perhaps even old (well, maybe except for "hardcore" Gen-1 fans…). And is that Megatron turned into a cannon?
