These games are fresh new takes on Ruby and Sapphire, so we might be getting a BW2 type of story.

In addition, it seems Kyogre, Groudon, and Rayquaza will be getting megas.

While this can't be 100% true, it does make sense, especially with the new 3rd gen. games announced.

So that means Swampert and Sceptile may be getting megas, as Blaziken only getting it didn't make sense.
