Ant Man in Avengers Sequel? But First! Ant Man movie!

Edgar Wright, one of my favorite people on the planet, who has brought us Shaun of the Dead, Spaced, Hot Fuzz, and Scott Pilgrim Vs. The World, has been attached to an Ant Man movie for quite some time, but we never saw much movement on it. Until Edgar himself posted this tweet a few days ago.

And he stated "Received this in the mail. What does it mean?"

Now to add onto the speculation, an Avengers sequel has been announced, with it being rumored to be released in either 2015, or if I had to guess, 2016. But, Marvel does have an untitled film scheduled for release on May 16th of 2014. Could that date be for Ant Man? Just in time to be introduced to the world to join the Avengers in their sequel? We shall see.
