So here's a little one to start with.
We know that Black Widow is going through its Last Days ahead of Secret Wars.
Well, as a founder member of the Marvel Cinematic Universe version of The Avengers, she wasn't going to be away from the spotlight for long. And, just in time for the Avengers: Age Of Ultron DVD/Blu Ray, I understand that a new Black Widow comic will launch written by Mark Waid.
Waid currently writes the SHIELD book for MArvel, so there is plenty of opportunity for crossover there.
Marvel Comics didn't respond to enquiries.
