Seems to me the most likely thing to happen is that they introduce the Odin battle as a challenge at the fan fest. Something cool for the attendees to be world first to challenge it. The 15 minute time limit is too similar to something like this. It makes sense that they wouldn't have mentioned it yet at the live letter if they want it to be a surprise. Of course it's hardly a surprise if the data is in the patch already. But they are remarkably clueless about this stuff it seems. Like "we're not going to introduce a way to keep track of the light on your relic, we want to keep it vague" when an app came out to do exactly that days ago.
Then I think they will reveal a full hm/ex primal battle for Odin in either 2.4 or 2.5 because I don't think they would put assets into developing a whole new primal battle just for the fan fest. Plus there's the sliepnir reward as well which you would randomly get, something that's not available at a fan fest challenge where you aren't playing your own character.
