After leaking multiple times, here's the official trailer for Decidueye, Incineroar and Primarina, your final starter evolutions. Here are the official descriptions:
The Arrow Quill Pokémon Decidueye is the fully evolved form of the Grass- and Flying-type first-partner Pokémon Rowlet. Decidueye attacks with astonishing speed, plucking arrow quills from its wings to send them hurtling towards its target with precise aim. This Pokémon is able to move about whilst completely masking its presence from others. Decidueye is the only Pokémon that can learn the move Spirit Shackle. This new Ghost-type move hits an opponent and makes it unable to leave the battle -- it can't flee or switch out.
The Heel Pokémon Incineroar is the fully evolved form of the Fire-type first-partner Pokémon Litten. As Incineroar's fighting spirit increases, the flames it produces within its body burst from its navel and waistline. These flames resemble a championship belt, which it uses to unleash its moves. Incineroar is the only Pokémon able to learn the move Darkest Lariat. This new Dark-type physical attack allows Incineroar to deal damage to an enemy whilst ignoring the effects of any stat changes on that enemy.
The Soloist Pokémon Primarina is the fully evolved form of the Water-type first-partner Pokémon Popplio. As Primarina dances, it releases balloons of water and controls their movement using the sound waves from its voice. Primarina uses some of these balloons to jump on and manoeuvre in battle whilst others explode when touched, which can trigger chained explosions. Primarina is the only Pokémon that can learn Sparkling Aria, a new Water-type special move which heals the burns of any target it strikes.
In case you missed the Pokemon Sun and Moon demo leaks, the final evolutions of the starters were apparently leaked once again via Pokemon's official Japanese Twitter account last night.
The tweet has since been deleted, but it originally featured the following Sun and Moon card game art.

Which also included the names of the final evolutions: ジュナイパー(Junaipaa), ガオガエン (Gaogaen) and アシレーヌ (Ashireenu). Those have obviously been changed for the Western release.

These evolutions looked like leaked art from this winter.
Here are screengrabs of the now MIA tweet:
So many leaks!
