Ex-Acclaim Dev Gives Closer Look At The Cancelled SNES Title 'Mortal Kombat Nitro'

Gameplay footage start around the 21 minute mark. There might be more earlier, but I skipped to there and it seemed to just be starting.

Seems crazy to me that they were considering this, given that there was only 1 year between MK 1 & 2. It could have ended up like the Street Fighter II situation, with new versions constantly getting released with minor updates.
