Chefen for 343 Industries, Bonnie Ross, siger i et interview med OXM, at studiet på sigt gerne vil droppe numrene fra Halo-seriens titler. Det er derfor Halo 5 bærer undertitlen Guardians.
"At some point, we do want to stop numbering. Especially on Xbox One. If I had my druthers, we wouldn't have called Halo 4 that - we really look at that game as the start of where he's going. At some point we need to drop the number and still (let you) know you've got a big story coming."
Hun fortæller også hvordan hun ser Halo-seriens fremtid, og at ikke alle spillene behøver handle om Master Chief.
"I'm just saying, at some point we don't want to be Halo 17, when Master Chief's like 80. We're not Final Fantasy, we can't do it. So we kind of open that door - it doesn't mean it'll be a Master Chief story or not. That's something for us to decide in the future."
