Speculation Darth Traya in Star Wars Rebels Trailer

In the new Star Wars season 3 trailer, we see a ghostly apparition appearing to Ezra just after the scene showing him open the Sith holocron. Here is an image:



Circulating rumours of EU characters being reintroduced to the canon narrative have been confirmed with the revealing of Grand Admiral Thrawn in his original glory. Judging by Filoni's interviews, it appears as if more EU characters will also be canonised: with many speculating Kreia to be the likely candidate. This apparition certainly does look like Darth Traya/Kreia, she has the elderly appearance, straight white hair, the eerie eyes Kreia possessed, and it appears she has same robe as Kreia which reaches her jawline. Here is a comparison image:



Given that Malachor has been canonised and the holochron was also found here, I think it stands a chance that Kreia will be placed into the Star Wars canon and may possibly guide Ezra on her complex set of moral philosophies.
