Pokemon Omega/Alpha Groudon And Kyogre Mega Evolution? Or Mind Control?

Witnessing the covers of the newly announced Pokemon Games Omega Ruby And Alpha Sapphire... I noticed something. That the markings on them remind me of the time Pikachu was put under mind control. He has similar markings on him. The marking of Omega. In this particular scene he used these markings to summon Groudon. Could this have something to do with the plot of the game? It was originally speculated that these new forms on the covers were Mega Evolutions, but now look like something else. It is very possible that it is just Team Magma/Aqua controlling either Groudon Or Kyorge.

If this is true then this could turn out to be an exiting Pokemon adventure, or lets say they ARE Mega Evolutions. They do not look that different from the original. Just added some markings. If they are Mega Evolutions then Nintendo has stopped getting creative. Which is unlikely. These new forms are to plain to be Mega Evolutions. In fact the only legendary that has a Mega Evolution is Mewtwo. Thats only because of him being the Most Powerful Pokemon (Next To Arceus). This is just a theory, but it might prove to be true. There is no way to be sure until the game comes out, but that would make for an interesting plot.
