I can see Fox releasing the original, original trilogy around the time of Episode VII to take advantage of the Disney advertising. That would be fine by me. Lucas saying he made the deal to protect legacy of his work makes complete sense.
I felt more satisfied from the sizzle reel than the Affleck movie. That said, no reason why a street level film can't work in the MCU. Not every film they make needs to be an earth shaking event. The more personal stories will only add to the overall universe.
