3. It Might All Be Leading To A Reboot
Marvel has been building to Earth's Mightiest Heroes clashing with Thanos since the end of The Avengers in 2012, and with many of their actors' contracts nearing an end, it's been claimed that Infinity War will not only bring an end to Phase 3, but also that it will be an end of an era for the Marvel Cinematic Universe, leading to some sort of reboot or relaunch. However, don't expect Marvel to start from scratch. Kevin Feige has said on a number of occasions that they will recast their characters rather than reboot them (think Edward Norton/Mark Ruffalo). He also recently revealed that some actors have signed new deals, so however many new faces enter the fray, expect some familiar ones to stick around.
