Primal battles in 2.0

[Catapult]

Yep. They'll be set up as roaming NMs which takes you into an instance (which defeats the purpose of making them roaming...)

So the fights that exist now won't exist in the same way in 2.0, probably just the ones regarding Relic, (extreme/garuda) but even then Yoshida said they'll make adjustments to the quest in 2.0, so who knows.

Just pointing out that the part I've put in bold remains unconfirmed speculation. There is certainly a good argument for it being true, but so much remains completely unknown. The next clue will come when they release the list of achievements that can no longer be obtained in 2.0. If "had me some fun" (beat Ifrit in the bowl of embers) is on the list then we'll know.
