Really? Got a source confirming it's the pretty much identical robe that Revan wears in SWTOR they are trying to get it closer to? Seems pretty clear to me that they mean the original robe, the actual robe, not the reskin.
I need a source that the robe he is wearing in game is canon? So he's been wearing a placeholder this whole time?
It's only clear to you because that's what you want it to be. It's not what they said.
