question about the symbol in halo 4 trailer

Games Other Halo
1

i was thinking about something at the end of the halo 4 trailer it is the didact’s symbol before it turns upside down indicating another being, but i want to know why 343 has made it where the body of the symbol is attached to the border, shouldnt both the didact and the inverted symbol look this

and not

so i was thinking maybe its just 343’s new design for the symbol but i then thought that kinda wouldnt make sense as in the 10th terminal in halo cea 343 used original style of the didact symbol,

For a specific reason that we will likely find out during the game.
There are two Didact as well.

The symbol from the trailer is indeed a variation of the Didact’s symbol. It’s flipping represents the Didact’s “Unbound” state, according to Frankie. What all this means likely won’t be known until the game releases. However, as erickyboo pointed out, there are actually 2 Didacts, so I’m sure this will feed into the different symbols and the actual meaning of the unbound state.

we will find out who the inverted didact symbol belongs to but i doubt well find out why its a different style from the usual forerunner symbol.
