Studiosjefen for 343 Industries, Bonnie Ross, forteller i et intervju med Official Xbox Magazine at de etter hvert vil slutte å sette et nummer bak Halo-spillene, og at dette var grunnen til at Halo 5 fikk tilleggsnavnet 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."
Deretter forklarer Ross hvordan hun ser på fremtiden til Halo-spillene og det faktum at ikke alle kommer til å 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."
