Actually, according to Boon, the game will follow on, but not be based on other games like MK9 did. Thats the reason why so many new faces will appear:

 TRMK:  So it's evident that this is not just going to re-tread old story lines like the last game did.

 Ed Boon:  Right it definitely progresses the story forward.
