Have the sun and moon starters evolutions been released yet?

Question

i have seen rumors and leaks, but do we know yet for sure what the sun and moon starter evolutions are?

Comments

There is the 1 leak that has all the hallmarks of legitimate Nintendo internal content.  The Robin Hood archer owl, the pro wrestler tiger, and the mermaid.  Not confirmed, but there has yet to be an argument against it.

Decidueye, a Grass/Ghost type, is the final evolution of Rowlet.

Torracat, a Fire type, is the first evolution of Litten.
Incineroar, a Fire/Dark type, is the final evolution of Litten.

Brionne, a Water type, is the first evolution of Popplio.
Primarina, a Water/Fairy type, is the final evolution of Popplio.

No, the official evolutions for Rowlet, Litten, and Popplio have not been revealed yet.
