6th Gen Mega Pokemons

so about gen VI only adding about 70 Pokemons to the generation 6 which is far by the most lowest added pokemon throughout gen 1 - gen 6
but not that it added Mega Evolutions
so about the Mega Evos
it's only about 20 - 25 I think?
do you think there's still be more Mega Evos only hiding in a dark secret place in the pokemon data files?
that are only obtainable to Events?
I mean if you look at the Torchic event it became hotcakes in every players in X/Y
do you think Gamefreak tested it out to see if pokemon will make a lot of sales so they can distribute more event pokemons holding an exclusive Stones?
or it will be only in about 20 - 25 no more added to the future until gen 6

Discuss!

I believe that Gamefreak will put a few more Mega Pokémon through a event with the Mystery Gift. And I also strongly believe that there will be a good amount of new Mega Evolutions in their third game.
