Which as I mentioned previously is unlikely - the Buster Sword is already in the game as the animation for the Level 1 and 2 melee Limit Break, and Masamune I am almost 100% sure SE are keeping carefully in reserve for a future relic for SAM, as the name is a reoccuring weapon throughout the entire FF series dating back to the original FFI and is not just associated with Sephiroth (it was the mythic great katana for SAM in FFXI for instance).

So sadly they're unlikely for a hypothetical FFVII crossover event.
