UPDATE: We now have info on more upcoming episodes thanks to an extended preview. Some shots of the new episodes from the preview are below!
Thanks to some Bandai projector toys, we can confirm the Kami Trio will be in the anime this winter, probably in December. The page from Bandai's gachapon catalouge states under the trio, "Gachapon first appearance! Linked to the TV Series! Lineup of major-attention Pokemon with huge activity this winter!"
Please notice that the other Pokemon shown (the snakes and birds) have all appeared as gachapon before, so it would seem it is specifically referring to the trio!
My guess of December is based on Tomy MC Figures of the trio coming out on December 17th!
Tomy MC preorders:
Very exciting?!?!?! Yeah!
