1. Planet Hulk
It's already been confirmed that Avengers: Age Of Ultron will end with the Hulk no longer on Earth. An earlier draft of the script apparently had the Green Goliath rocketed into outer space, but the sequel handles his departure in a way which means that he could easily be brought back to Earth should Marvel change their mind about making a Planet Hulk movie. Marvel can't make a solo Hulk movie because Universal still hold the rights to those, so the Planet Hulk storyline will more than likely become part of the Guardians Of The Galaxy sequel. This would be a smart way to tie that and the Avengers franchise together, and the Hulk leading the Guardians to Earth to take on Thanos in Infinity War would be perfect.
