I was browsing through Tumblr a few minutes ago and came across this, it's apparently some middle stage evolution for Fletchling:
It's a Fire/Flying-type like Talonflame is, so I guess that confirms a 3-stage evolution line with Fletchling evolving into Fletchinder (the Pokemon shown in the pics) and then finally Talonflame. And it also appears to learn Ember, Quick Attack, Agility and Peck. Fletchinder's name is 11 characters long, so that means we no longer have a 10 character limit for Pokemon names, I was expecting it since Pancham's French name was also revealed to be more than 10 characters long. And on the bright side, I was expecting some middle stage evolution for Fletchling as well, I knew Talonflame wouldn't directly evolve from Fletchling and there'd be some middle stage inbetween.
I also found another screenshot that I since reblogged to my Tumblr page, and it showed Spritzee being revealed to learn Echoed Voice, Sweet Kiss, Fairy Wind and Odor Sleuth.
