Pokemon studio teases 'surprise collaboration'

The House of Pokemon is teasing a mysterious new collaboration. A new webpage from Game Freak shows, we dunnno, a glowing baby horse silhouette or something in front of some Japanese text. We do know what the text says, at least, thanks to Gematsu:

“That classic game played around the world is reborn in a surprise collaboration.”

Pokemon teamed up with Koei tactics series Nobunaga's Ambition for Pokemon Conquest last year, so another crossover seems likely. Looks like we'll find out soon.
