Ok I'm taking this with a sack of salt as the author didn't quote the origin of this, but here's meristation coverage on Mortal Kombat during the E3.

Meristation is a spanish website dedicated to videogames coverage:

The part I want to focus is this:

"También sabemos que habrá un modo historia, en el que Scorpion y Sub-Zero tendrán un papel decisivo, debiendo formar equipo tras descubrir el primero que Sub-Zero no fue el responsable de la muerte de su clan, sino su maestro Quan Chi."

Which translates to:

"We also know that there will be a story mode where Scorpion and Sub-Zero will play an instrumental role, having to team up after the first one discovers that Sub-Zero wasn't responsible of the death of his clan, but his master Quan Chi instead."


As I said I'm taking this with a huge sack of salt as I can't find where he's getting this information from (and the video isn't available because of an error code...), but if this is true I would love to see their grudge finally ending as it was the logical path for Scorpion to finally stop being dumb and see things as what they're. This would also confirm Kuai Liang as Sub-Zero and as both are currently in netherealm it could lead to both meeting and later teaming up.
