Today retailers across the country have received a postcard from Marvel Comics, signed by Editor In Chief Axel Alonso, tell them that something is happening.

What is?

No idea. But whatever it is, it's coming. Look.

Whatever it is, it will be revealed at the Cup O' Joe panel at 5pm on Saturday, October the 15th during the New York Comic Con.

And there will be a live blog at marvel.com/itscoming.
