This is probably old news to folks deeper in the Halo fandom than I am at the moment [and definitely old news by the time I cross-post this], but: that AI chip that Master Chief is shown slotting into his helmet at the end of the Halo Infinite trailer? There's a chance that it could be a version of Durandal. And this was confirmed by two community leaders, to boot.
</span>For obvious reasons, I hope that this turns out to be the case. Doodled some related stuff (Durandal looks weird in blue, but that's the colour of the AI chip, so...Still gave his android self green markings)
