Pokémon Omega Ruby and Pokémon Alpha Sapphire announced

Also, do you guys think the box art is supposed to be of Groudon and Kyogre in their mega forms?

I was thoroughly convinced that they were Mega Evolutions when I first saw the announcement trailer and the brief few moments of the games' boxarts. Then in one of the announcement threads I was reading, someone did a comparison picture and it's pretty clear that thatGroudon and Kyogre are quite different than the normal Groudon and Kyogre. I'd say it's a safe bet that those are Megas.
