Is this "Crocodile Dundee" sequel legit, or a stunt?

A mysterious teaser trailer dropped over the weekend for a totally unexpected Crocodile Dundee sequel starring Danny McBride. 

Now another trailer dropped with Chris Hemsworth in the newest trailer. While this looks like it could be believable most Dundee fans are skeptical this is just a stunt for the Super Bowl. 

I guess we'll find out soon.
