"When Twilight casts a spell that switches the Cutie Marks and destinies, the only way to reverse the spell is by writing her own magic."

This is the summary of the future episode in which Twilight will become an alicorn. Reading over makes me think that Twilight isn't going to be an alicorn permanently; she probably "switches" her cutie mark and/or destiny with one of the princesses, and by the end of this future episode, she'll go back to being a regular unicorn.
