The latest trailer for Pokemon Omega Ruby and Alpha Sapphire comes packed with a ton of new details about the Ruby and Sapphire remakes.

The trailer reveals three new Mega Evolutions, including Mega Altaria, Salamence and Lopunny. Mega Altaria will be a Dragon/Fairy type where Salamence and Lopunny will maintain their Dragon and Normal type after Mega Evolving.

Contests will be returning in Omega Ruby and Alpha Sapphire, and the Mega Evolution mechanic will play into them if you manage to impress the crowd enough.

Hordes, battles against groups of wild Pokemon at once, will be migrating from Pokemon X and Y into Omega Ruby and Alpha Sapphire.
