At the end of Legendary Halo 3, we see Chief drifting into space towards what looks like a relic planet. There are multiple reasons for this. We know that he will be on a broken ship in cryo-stasis. While his body may be frozen, his mind will still be working, therefore, i believe that Reach will be a flashback of the past events. Or, it will be a recollection on Cortana's part filling in what John missed. This sets Microsoft up perfect for later games. John will awake from this flashback on the relic planet and time for a new game!
