*SPOILERS* - for pretty much every main quest

(Yeah I know it's been a while but still don't want to accidentally ruin it for people)

The only thing really close to a retcon is the switch from Warframes being an exoskeletal suit the Tenno wear to the Warframes being a biomechanical construct controlled by the Tenno via Transference. However they can easily explain that away in universe as the 'original' lore being what the general public thought was going on, and the 'new' lore being what actually happened with only the most elite of Orokin and the scientists who worked on the project knowing it.

To me the Rhino Prime codex entry is a clear indication that DE had decided on something close to the lore we have been given through Second Dream by that time. What is attacking them is the fleshy infested base of a warframe without the metal plating and electronics grafted on yet. When it hits the room with the Tenno in it the close proximity allows for what was probably the first recorded instance of transference with one of the children taking control of it. Thats why its behavior changes so radically, because its no longer being driven by infested instincts but by a child that probably doesn't understand what is going on.
