Except that Bungie didn't plan Halo 4 or Halo 5 as they completed halo development work with Reach. Had the blueprinted some of the IP being used by 343 for the 2nd trilogy in the "Halo Bible?" Maybe, but to make a statement that the core elements of Destiny were being developed for a yet to be released game 6 years ago couldn't possibly be true unless Halo 5 ends up being Duke Nukem Forever
