So, since 343I got given free reign what have we had so far?

Flood being a parasitic powder for pets.
12 Halo rings.
Prophets and human having an alliance.
Humans going to war with Forerunners.
Humans having cure for Flood parasite.
Halo's now have wings/fins
Humans are still at war trying to cause extinction of the Elites.
Flood being the super mythical precursor or at least having some connection to said precursor race..

Have I missed anything?
