E3 2015 - Shin Megami Tensei X Fire Emblem Trailer

While it's sparse on details, Nintendo revealed a crossover between two of its biggest JRPG franchises: Shin Megami Tensei X Fire Emblem.

They're not exactly similar universes, but between Smash Bros. and Persona 4 Arena games Nintendo is clearly no stranger to pulling a deus ex machina and fudging some details for the greater gaming good.

Beyond the fact that it exists, Nintendo didn't reveal much more about the upcoming game, which will land on the Wii U and is currently in development.
