: My number one thought was the concepts for the Guardians themselves. The one
: early concept is almost identical to the hologram on the H3 map Epitaph,
: and the Guardian Sentinels we see in Origins... so I wonder now if the
: Guardian Sentinels have now canonically become separate from the
: Guardians, or if they remain the same, just in different shapes for
: different functions

Yeah honestly I think changing them was a mistake. The vaguely birdlike design in the trailer, too, seemed more interesting to me than the grinning skull face we got.
