Has the new Overwatch hero been revealed?

Blizzard has been teasing new content for Overwatch recently, and now a new tweet has been posted, simply with the caption: "The champion revealed."

The video attached shows a giant rolling mech, and out pops what appears to be a hamster or chipmunk of some description, but because this is a little unexpected to say the least, people have been asking whether this is a troll, which the Overwatch Twitter account has responded to by dodging all these questions.

It seems as if this could be correct though, as we may well be looking at Winston's friend Hammond, which fans have been speculating at for a while, although few would have predicted this is how he'd look.

We don't know what's going on, but we hope to find out soon. Do you want this to be the new hero?
