Re: So what will be this Preventable Event?
Actually I think it will be JFK.
We got a clue about it awhile back, with a quote that said the sequel would focus heavily on Magneto (being responsible for the magic bullet).
Im guessing they have to prevent Magneto from killing JFK in order to save the future we have seen in the established trilogy, while trying to prevent a timeline that occurs due to a Mutant killing Kennedy - which will include some form of Sentinels or Mutant Death Squads.
