TF2 Meet the Pyro / Mann Vs. Machine Update

It appears that there is another Valve ARG that has started leading up to the Mann Vs. Machine update. As of this initial typing they want people to craft two banana peels together and post the error code it gives you here

Go here to see the latest on the ARG

We're not SURE it's the Mann vs Machine update, which isn't even an official name. Some say it's Meet the Pyro. Some say it's TOBOR (aka mann vs machine). Some say it's neither or both.

Or more likely, it has to do with Adult Swim and Meet the Pyro.
