I hope in the next expansion they'll bring back Odin/Zantetsuken.

I thought the way it ended initially seemed rather anti-climatic and unfinished in some capacity? (I suppose its for the whole mystery surrounding this Primal).

If not that then I hope we will get some Unreal Version of him.

It was one of the few things left behind in ARR that bugged me aside from the Heart of Sabik (which finally got answered), so hope they will expand on Odin later.

More info on Odin exists in Eureka, though I shall not say more for risk of spoilers.

[Canadane]

They could still bring it back in the current expansion.

[KageTokage]

Even with the new information in Eureka, Odin largely remains an enigma.

*Bozja spoilers*

I'm half-expecting that we might learn more about his nature considering that we're going to be dealing with another primal in weapon form with Save the Queen, though.
