Marvel Studios has been pretty blatant that things are going to look very different for the Marvel Cinematic Universe going forward. Phase 4 and beyond is a new beginning and that means that Avengers: Infinity War and Avengers 4 are going to be an ending. Joe Russo recently spoke to the Hindustan Times about the Marvel Universe and Infinity War being the final chapter.
"For me, this Marvel Universe is like a book. It has been in writing for last 10 years with all these films. Infinity War is the final chapter in this book. So, in the future, there will be new stories to tell. In the future, we will be seeing a new beginning. Black Panther is one of them and it is so incredible. The future of Marvel is going to be a lot more diverse catering to fans across the globe. People have been (living) with these characters for a decade and this is the ending. It is very exciting as there is a sense of closure and then also of new beginnings," he says.
As Russo says this isn't just an ending for the people involved this is also for us. There is an entire generation of kids that have grown up on these movies and now we have to see it all end. It's a big deal and it's good to see that the people making these movies understand that.
Summary: As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality.
