Halo: Reach Discussion
There is definitely not a Spartan 4 Program due to the fact that the war is over. And no-one knows what the ancient threat is otherwise there would be no hype!
(Read the whole thing, or skip down to Halo 4)
Halo 1: Introduction of the game, you fight Covenant&Flood for the first time. You blow up the first Halo.
Halo 2: Covenant find earth, you then stop a second Halo from firing, putting all other rings on standby.
Halo 3: You fight the covenant and flood on Earth, then go to the ark to activate the ring there to destroy the flood, and also save Humanity. At the end Master Chief is separated in half of a frigate, floating in space. On the legendary difficulty, there is an extra clip, showing the Frigate drifting towards an unknown planet. THIS sets up Halo 4.
Halo 4 is most likely going to be based on Onyx, the "Shield" in the Forunner's plan. (Halo's being the sword.)
Most likely the Master Chief will meet up with other Spartans trapped on Onyx (The Spartans became trapped during the Halo book: Ghost's of Onyx). From there god knows what. That's my guess, but I doubt anything will happen on Earth. It is possible though.
Once again this is all speculation based upon the Legendary ending to Halo 3 and the Halo lore (Taken from the Halo books).
Lets wait and see
Also there will be a halo 5 and 6. Halo 4 is marking the beginning of a new trilogy for the Halo franchise.
