Nah, that is not enough.~
So far the Hoenn region and the Unova region still have no Pidgey family in their respective regional dexes. :'(
On the positive note, existence of Mega Pidgeot been confirmed. Several regions, like the Sinnoh region, have Pidgey appearing as one of the swarm Pokémon.
Ganbatte, Pidgey-kun! Make the tribe feel proud!~
