Ok, so I haven't read any of the books, but I think I have the plot of the video games nailed down... spoilers incoming
Halo: Reach > Halo: Combat Evolved > Halo 2 > ODST > Halo 3
Halo: Reach - "ends" with you handing Cortana off to Keyes aboard the Pillar of Autumn. You can see Master Chief all cryosleeped up. Halo: Combat Evolved begins with you waking up and learning how to use your brand new original xbox controller. yay!.
Eventually, Halo 3 ends with you drifting in space aboard half of the Forward Into Dawn. You go back in to cryosleep, and tell Cortana to wake you when you're needed.
Halo 4 = you're needed.
So, different ships, different cryosleeps
If you finish on Legendary, it just shows the ship floating towards another planet.
