Two styles of battle: The turn-based style everyone's familiar with, and a real-time one where timing/pacing is key; your shout commands and your Pokémon reacts accordingly. Can dodge and combine moves, just like the anime. It'd remain slow and methodical, yet engaging and reactive at the same time.
At least 8 sq. miles of fully-explorable landmass. Deserts, mountains, dungeons, underwater areas, and everything in between.
At least 29 fellow players on screen at a time in the overworld, kind of like GTA Online.
Buff all weaker Pokémon across the board. Redistribute their stats or simply increase them.
Z-moves and Megas return, the latter being toned down a couple of notches.
No longer being forced to wear silly uniforms when riding your Pokémon/bike.
Actually long-sleeved apparel that covers the wrists. And better clothing in general.
Make monotypes more worth using by increasing their STAB bonus or decreasing the bonus for dual-types.
BOTW art-style on the RAGE engine. It can handle so much, even on the base XBox One. Wind and cloth physics. Imagine your Pokémon's ears/appendages flustering in the wind.
Overworld and following Pokémon. Amie/Refresh/Camp is no longer an instance and Pokémon can be sent out anywhere as long as there's space.
Accessories and clothing for your Pokémon. Customizable age and body-types. Skin tones that aren't too dark or light this time around.
New Game+/difficulty settings that don't require losing your Pokémon.
Camera/Theatre Mode.
Natures no longer affect stats.
In addition to everything
