I think this makes sense especially since its been given away that Twilight's destiny will be revealed and I'm hoping for something really epic! Two episodes will not be enough it has to be three. There's also the fact that the last three episode titles haven't been revealed.

Most likely just two...

I doubt Hasbro's going to allow a 3-parter. it's always the usual trend that, whenever there's a premier, finale, or special episode, it's usually just a 2-parter

Looks like it was a 1 parter....[/b]
