We don't know if the royal sisters and Discord are immortal, they could easily just be (very) long-lived. For that matter, we don't even know what the average lifespan of a normal pony is. And the only thing we know about how long Twilight will live is that she will not outlive her friends; that statement says nothing about the possibility that her friends' lifespans could be extended right along with hers.
