Random facts about Mario, Kirby, Sonic, Zelda and Pokémon

Fact 54 (a theory)

We might be getting a Kirby Air Ride sequel next year, as it is the 25th anniversary of Kirby, and many games are using content from the game:

Triple Deluxe/Kid Icarus Uprising/Smash Bros. using the same panel system
Kirby Air Ride music playing during Rosalina's Smash 4 trailer, and Mario Kart (a similar racing game) being shown
Smash Run is pretty much City Trial 2.0

Thoughts on the theory? I know it isn't really a fact, but has anyone else noticed this?
