1. West/Central/East Sinnoh story and region strucutre. Resembles the Islands and the Tapu Four of Alola, as in exploring the region in clusters based around the Lake Trio. Shuffling Sinnoh's gym order and making it easier to navigate thanks to Pokeride definitely is something I can see them doing. Gym order would be:
Oreburgh
Canalave
Eterna
Hearthome
Snowpoint
Pastoria
Sunnyshore
Veilstone
Basically, think of each part expanding on the Emotion(Barry)-Knowledge(Prof. Assistant)-Willpower(PC) angle for the storytelling, with Parallels to key characters of each part(Barry and Roark's emotions of being in their father' shadow, the assistant and Cynthia's hunt for knowledge, and the duality of the PC and Cyrus when it comes to the story).
2.Sinnoh Underground gets an online mode, and can be used for fast travel later on.
3. Festival Plaza Hub in Jublife as a nod to the GTS locale.
4. Post game has a bunch of minisodes for the event legendaries, and Giratina. Like think DPt but on steroids. A bit more expanded Darkrai and New/Full Moon lore as well as mixing in Riley, same thing with Shaymin and Marley involving Floaroma as well. The big one would be similar to Rayquaza and Deoxys involving Giratina and Arceus that acts like an epilogue mixing in the DP ending continuing into a small story that sees Cyrus try one final time to reach his goal, ending finally in the way Platinum climaxed. A Charon minisode would also mix in Cheryl to have all the minisodes involve the stat trainers at post league levels, basically introducing him through Eterna Forest and the Old Chataeu, and ending with the Stark Mountain part.
Rotom Poketch. Dead serious here, I think if theu give it a color screen and have the same functions of the RotomDex, minus the Dex, while keeping all the widgets of the Poketch it could be something amazing.
