343 trying to replicate the original trilogy?

So I think I’m on to something here. In Halo 4 Chief lands on a mysterious planet, like in Halo CE how he also lands on a mysterious planet. In Halo 5 there are two points of view on the story (Chief and Locke), like in Halo 2 there were also two points of view (Chief and Arbiter). I believe Halo 6 will have some resemblance to Halo 3. Am I correct or are these just coincidences?

I can agree with you, maybe in Halo 6 there is no any more Elites as enemies (like Halo 3). Halo 5 we see Covenant civil war (like Halo 2) between Sword of Sanghelios and Jul Mdama’s Covenant Remnant Faction. In Halo 4 there are same Covenant species than in CE (Elite,Grunt,Hunter,Jackal) and same amount of Promethean types than Flood forms in CE.

And 2009 came out two Halo games:
Halo 3: ODST
Halo Wars

And 2017 are maybe coming two Halo games:
Halo 3: Anniversary
Halo Wars 2

What is 343 trying to do?
