Well, that's pretty hype.
A new way of interacting with players that gives you items and enhances your Pokémon.
New evolutions for the starters.
The Z-Ring can activate Megas, but Megas still need the Mega Stone, so they can't use Mega-Evolution. Unless they're Rayquaza. Because OP.
Ash-Greninja for playing the special demo.
This is a pretty hefty update.
