1. Yay, we have Gen 7 coming during the anniversary year.
2. With Red/Blue/Yellow getting Pokémon Bank support...
a.) I'll be curious to see their natures/abilities when transferred over to Sun/Moon.
b.) Easy legendary bird catching/leveling, since we've got unlimited Master Balls/Rare Candies. Thanks, Missing No!
c.) I wonder if Pokémon GO will also have benefits connected to Sun/Moon.
3. With enhanced sequels fulfilling the "iPhone S" role of testing new ideas, "third entries" are no longer necessary outside of story reasons (Black 2/White 2). The lack of Z is understandable, and I'm sure those Zygarde forms will surface in Sun/Moon.
One more thing: That Snorlax pillow. I need it.
