Are the Avengers Going Global?

A new teaser from Marvel Comics for their upcoming panels in NYCC shows the word GLOBAL with a green hue.

And more importantly it boasts of a stellar creative team. 

So yeah, we got Jonathan Hickman, Nick Spencer (who's doing Secret Avengers) and Stefano Caselli who was also working with Avengers prior to INFINITY.

So what could this be? I've been reading the comments from various groups and it feels like they're on to something.

- It could either be a new expansion for the Avengers i.e. taking in new members from other superteams from around the world like Alpha Flight or Big Hero 6. 

- It could be a Hulk-centric storyline which is kinda dumb in my opinion.

- It could tie up to whatever will happen in the next Avengers storyarc featuring a renegade planet on a collision course with Earth (which would be interesting and solicited as well). 

Either way, NYCC is just around the corner so let's just play the waiting game.
