The way things have been translated for us it seems they aren't Mega Evolutions but another kind of alternate form called something like "prehistoric devolution" sounds like a power down but it's perhaps a return to their ancient more powerful (or at least somehow different) selves. What causes the form changes (stones?, the red and blue orbs?, or something else) is for now undetermined.
Well...according to lore, they were at some point responsible for creating the land and the sea, so...I doubt that they'll be getting any weaker. In fact, this could lend credence to the idea that they might just get some new perma-weather abilities. Devolution could very easily be a way to establish a separate mechanic for some pokemon, Legendaries in particular, that allows for them to give them Megas, but without trying to tie them all into the Kalos plot, and allowing them to change certain things, such as the stat changes. Add on fifty points, as opposed to one hundred, for example.
And before arguments come up that they wouldn't just nerf an ability to recreate what they just nerfed, consider this: Devolution to a primal form implies that Kyogre and Groudon have only grown weaker in their hibernation. Even before Politoed and Ninetales were given the weather abilities, and even before Hippowdon and Abomasnow, and their pre-evolutions, were created, Tyranitar was given Sandstream.
If you consider that Kyogre used Drizzle to create oceans, and Groudon used Drought to create land, and Sandstream followed the same mechanics of those two abilities, then doesn't that imply that a Tyranitar was on a level with these two legendaries, and could singlehandedly create arid deserts? What does that mean for a colony of Tyranitar? Then what does that mean about Snover? And yes, these are battle mechanics, but if a pair of legendaries are capable of terraforming a planet, then why would they only be able to hold that ability for a short amount of time, simply because they're in a battle? Why would they be constrained to that ability, if they are reverted back to the states that they were able to terraform with? Groudon and Kyogre are defined by the weather, and it's something that set them distinctly apart from every other legendary, both at their introduction, and in following generations. Dialga didn't an ability that affected time, for example, and could have worked similarly to Parental Bond. Ever since their introduction, however, this distinction has become less and less significant as more pokemon with terraforming abilities have been established. Would it not make sense, then, to remove that sheer power from an ordinary fox and toad, and give it back to the beasts that are defined by it?
This is wholly from a continuity standpoint, but continuity is important in a world like this.

Wally should defintley get Mega-Gardevoir. One thing that always erks me a little is how much people sexualize Gardevoir. She not really supposed to be a sexy thing at all. She's more maternal, like a protector or guardian angel. A sickly boy is the perfect owner for her.
Apparently you deleted this, but I just wanted to say, This. This is a perfect description of Gardevoir. This exactly.
A Gardevoir is already established canon for Wally, so I would be expecting much of a change there. It was male, however, but I'm still not expecting much change. Maybe among his other pokemon, though; he had a Magneton and a Roselia, as well as an empty slot. Really, I don't expect them to, at least not until after the Elite Four, but the Hoenn games were really underwhelming as far as the rival battles went, and I really hope that they find a way to improve on both Brendan/May and Wally.
