my silly crack theory for Legends Z-A is that Xerneas and Yveltal will get Primal forms. my silly reasoning is this: Primal Reversion is associated with the beginning and the end of life on earth. the origin of life is associated with Kyogre because it occurred in the ocean — the "Primordial Sea". for Groudon, "Desolate Land" is actually an outlier among localizations, which mostly translate more literally as "Land of the End" (this includes the original Japanese).

Primal Reversion is a way that Legendary Pokemon become (or return to) manifestations of nature at the chaotic beginnings or apocalyptic ends of life — so it only makes sense that Xerneas and Yveltal could've had more powerful forms under those conditions, too. also: the title of the game is Legends Z-A, not just Legends Zygarde. they chose to use the last and first letter of the Latin alphabet — just like Greek has Omega and Alpha.

also x2: Dialga and Palkia got new forms in Legends Arceus, borrowing from Giratina's Origin Forme gimmick. Zygarde's Complete Forme gimmick isn't really appropriate for Xerneas and Yveltal, with the XY duo not being made of cells or anything, so if they get new forms, it should be either a totally new gimmick, OR a gimmick from their debut generation. this could absolutely mean Megas, but just personally I think Primals would be cooler for these legendaries in particular.

also x3: last but not least, Xerneas and Yveltal kind of have this "sleep in a tree/cocoon for 1000 years" thing going on that wouldn't line up with the timeline of PLZA, because those games are going to be set way less than 1000 years before Xerneas and Yveltal awaken in modern times. I don't fully know where I'm going here, but basically, it makes sense why GameFreak might want to drop in some new additions to the lore to help explain the discrepancy — idk, maybe either Zygarde or some happening in Lumiose awakened Xerneas and Yveltal off-schedule by allowing them to Primal Revert.
