Only a limited number of Pokémon in Pokémon X & Y can draw on the ability to evolve into their Mega forms during battle. With the limited Mega Pokémon, some of your favourites may not find their way into the newest entry on the 3DS later this fall.

YouTube user SkywardWing made a list of the five Pokémon he would love to see come with a Mega evolution in Pokémon X & Y. To avoid spoiling his list, I'll embed his video below.
