they will make more sequels to the halo franchise but they did call halo a trilogy I heard that their will be prequels with the forerunners trilogy. The grunt-hunter rebellion that was mentioned in halo 2. And ones that's will take place after 3 with the elites vs the new rouge brutes and also master chief after crashing on onix in the end of three ( onix is the planet where the other Spartans escaped to during reach please read ghost of onix ) but those are rumors that I heard acually allot of people are wrong about master chief being the last sparten in the galaxy there is a girl sparten 458 and a guy that I don't know his tag. And what would be cool is master chiefs brother.
