Killer Instinct 2 SNES

SNES was a different time. I bet that KI2 for SNES never left the Rare HQ.
Unless some ex rare employee leaking it (if somebody took it home) i see no chance that it will pop up at all.
However seeing how MS has reacted to the PD and Conker Betas i dont see a leak of KI2 at all.
