Nash ending Goldberg’s streak


How long was the plan in place for Kevin Nash to end Goldberg's undefeated streak while beating him for the WCW Championship at Starrcade 1998?  Was there even really a plan at that point?   

I'm sure Nash was planning on it for a LONG time.  And to be fair, they did a lot of preparation for him, like ending Wrath's own streak and stuff like that.  So at least a few months in advance.
