I would never personally believe any rumours or leaks. I need an official confirmation before I can believe. I've been burned so many times, been disappointed time and time again due to them being fake, so I've learned to stay skeptical. And I am normally not one to enable the behaviour of believing in these things...
But hey! It's the first we hear about anything MK11 related.
DO NOT BELIEVE THIS IS OFFICIAL WHAT SO EVER!!!
But enjoy it for what it is.
Let the speculations and theories begin!
