People are claiming that the starters Final Evolutions and types have been named.
Fire/Psychic - Fennekin / Flannec / Fernox
Water/Fighting - Froakie / Ribbub / Froabanet
Grass/Dark - Chespin / Chespike / Chespear
The image also shows a Pokemon group under the names:
Finches Forme X
Fincho Forme Y
This hasn't been confirmed, but I thought I would post it anyway.
In the trailer, look at :35.. Poor Magikarp getting hit with a Solarbeam.. Poor Magikarp, can't catch a break.
