So the Avengers like, assembled yesterday



And it was confirmed throughout the Con that the following would indeed be joining the project:

Jeremy Renner - Hawkeye
Mark Ruffalo - The Hulk / Bruce Banner

There was also some footage from Captain America shown as well as an early trailer for Thor

It's hard not to be stoked for this when everyone involved seems so excited that it's happening. Really looking forward to it
