Consider the following pokespe

I thought they dropped it because the designers were having an art block

They couldn't come up with a design on time, although legends za is coming soon with hopefully megas for Kalos starters

the only Megas that got leaked were mega zygarde and mega zeraora, I REALLY hope there’s more

also another interesting thing that got leaked is that there was apparently a flying type Eeveelution made for sun and moon but it got scrapped because it looked too much like a fakemon
