I as this because in Omega Ruby and Alpha Sapphire they had mega Camurupt and Mega Sharpedo. They were the respective pok'emon of each leader (Archie and Maxie) . In the original they had normal Camurept and Sharpedo and now they have Megas. If you look at the logos it looks like a form of Lunatone and Solrock in Sun and Moon. thats sun.
and thats moon.
Thx 4 any help and answers!
PS: Sorry for the difference in size of the images
The only thing we've got on Sun and Moon are a trailer, a logo, and a couple of names. It's impossible to say for sure.
