Guardians of the Galaxy: Marvel Teasing Footage Drop?

Could fans finally see an officially-released look at James Gunn's in-production Marvel movie Guardians of the Galaxy after two months of leaked footage from San Diego Comic Con International and D23 floating around? That's what it sounds like, based on a tweet from Marvel's Ryan Penagos ("Agent M"). Here's what Penagos had to say:

Just watched a Rocket Raccoon thing we're sharing soon and it's just so good I want to throw up rainbows and rip my face off. — Ryan Penagos (@AgentM) September 27, 2013

It's probably not the footage from San Diego/D23, since he singles out Rocket Raccoon--and could even be something unrelated, like an Ultimate Spider-Man appearance or an animated short. Still, we can hope...!
