That is absolutely a troll.
Yes It did. Thats why I reckon this will be a prequel of sorts.
Could be a prequel or it could be the events that are supposed to take place after MK9.
Remember, the MK3 part of the MK9 story skewed the entire timeline, so we may still see some things take place, while other things are new and not necessarily MK4.
You should probably wait to preorder until you see if there are collector editions
Just came across this interview with Ed Boon, sounds quite fishy, can anyone confirm if it is a troll site by any chance?
