Today would have been a great day to send an ingame mail to every character who has done Maelstrom Prison or the Foundry to inform us what really happened after Revan's Malak quote. It wouldn't even matter if the content was 1-2 years away.
In that mail could have been a Revan's Heir title, Ebon Hawk toy, Bastilla/Malak holostatue, Mini HK-47 pet, T3 pet....just to name a few ideas.
Cartel Market could have had Revan's current robe for one week....
I fear we're never going to get an answer regarding Revan's fate.
