Here's how we know this season won't end with a two-parter. (imitating Spencer from Burn Notice) There's a pattern! Every season has had some sort of arc of its own starting at or near the beginning and ending in the final... except one.

Season 1 - The Grand Galloping Gala

Season 3 - The "mysterious book" and what it is Twilight will be "that much closer to being ready for" (alicorn)

Season 4 - The mystery box, possibly the Equestria Games

Season 2 has not had a season-long arc and it ended in a two-parter with Chrysalis. Nothing led up to the wedding in ACW, not even introduction of Shining Armor or Princess Cadance. The closest we got is duplicate background ponies who may or may not be changelings.

So only seasons that don't have a season-long arc get two-part finals
