Mega Latios and Mega Latias have now been confirmed by the same ROM hacker who uncovered the three legendary Pokémon in X & Y which we reported on yesterday. Curiously they appear the same, reason has yet to be revealed. New Vivillon colors have also been uncovered! It seems AZ’s Floette could also come as an event Pokémon at some point as well.
ps- Layout change will probably remain through November because pumpkins are harvest-y 🙂
