Also, the orbit used to make that calculation may not yet be accurate enough to determine precisely where it'll be four years from now...

All Pluto's moons are orbiting at strongly resonant orbits. Nix, P4 and Hydra periods are multiples of the Charon-Pluto orbital period (as 1:4:5:6 to be precise) and therefore actual orbital position can not drift too much from predicted one. Actual flyby viewing geometry will be quite close to the mentioned above.
