Hopefully, they mean as in cameos, or in a prequel form.
The Chief is a soldier, and has no place in times of peace, so it's best his final fate is left unknown.

*Looks at "Finish the Fight" poster
so?.....The fight isn't over?
I'm reallly, really confused right now.
Yes, the "Fight" was "Finish"-ed.
The Covenant fell apart after the Hierarchs were all killed, so their campaign against humanity is over.
The Flood threat was neutralized (at least locally), so no more worries about a squishy, infected Earth.
It's only the Chief's story that has an open ending.

Also, with the Master Chief and Cortana drifting to an unknown planet (according to the after credits bit on Legendary), there has been fan speculation that the planet may well be Onyx (a place featured heavily in the novel Ghosts of Onyx, set during the events of Halo 3). Have Bungie or Microsoft released any information yet regarding that?
Who knows?
Maybe he found the Forerunner planet and he's now living like a god as their "Reclaimer."
