With Black Widow being pushed back to the end of the year, we have plenty of time to dissect the trailer for any and all secrets hidden in it!

I think not only are we getting General Ross as Red Hulk, but I think we may be getting an entire lineup of Dark Avengers! Get ready for some serious theorising folks!
