Pokémon Omega Ruby and Pokémon Alpha Sapphire announced

Something odd I noticed while looking at the E-shop:

Notice the pokemon shown in the banner.
Ignoring Pikachu, who is obviously there because it is the mascot, Audino and Lopunny are the most obviously strange, since they aren't Gen 3 pokemon, it stands to reason that they are there because they have new mega evolutions.
Now look at the other pokemon, who are all Gen 3 pokemon, yeah, but the choices are interesting.

Bagon, Shellgon and Salamence obviously now have Mega Salamence in their line.
Metang also obviously has ties to the new Mega Metagross
Altaria too
the Treecko, Mudkip and Torchic lines are also represented, who also have mega evolutions
and so do Groudon and Kyogre.

So the inclusion of Flygon, Feebas, Milotic and Makuhita seem strange. Until you consider that Milotic was shown frequently in trailers for mega evolutions, and Hariyama shows up inexplicably among the fully evolved starters in the big boss fights in the demo.
Can't remember if Flygon showed up in trailers but it probably did.

It probably means nothing, but it's.. interesting.
