It's great to see S.H.I.E.L.D. and the Quinjet, but is it too much to ask for Avengers Mansion?  Earth Mightiest Heroes resided at their official Central Park Headquarters for almost 40 years before temporarily moving to Stark Tower a little under a decade ago.  The building has been destroyed more times than you can imagine in one battle after another, but somehow disaster insurance still keeps covering some incredibly quick rebuilding efforts. The trailer seems to insinuate the Avengers will meet at a S.H.I.E.L.D. base on an island near New York (similar to the set up in Marvel's alternate series, "Ultimate Avengers").  We're still hoping the end of this first movie finds them moving into new Avengers Mansion digs.
