Mega Rayquaza Confirmed for Pokemon Ruby and Sapphire Remakes

Rayquaza is the latest in a long line of recently confirmed Mega Evolutions, with Sharpedo, Camerupt and Gallade being the latest. A few months back, Nintendo filed a trademark for Pokemon Delta Emerald, implying a remake with Rayquaza as a mascot could be in the works.

Pokemon Omega Ruby and Alpha Sapphire are coming to 3DS on November 21st.
