I'm hoping for this game to go back to the regular gyms and elite four members, instead of what they did with trails and the champion cup. Not that I don't want GF to change the things up a bit, but I'd rather them not change that original setup for every single game going forward. Instead, I'm hoping the changes will be more in the plot, new environments, features, and improved gameplay. And I definitely don't want them to do what they did with the badges in SwSh; that seemed rather lazy.
Other than that I just hope the games are good and have a solid roster of new Pokemon. Hopefully they'll mostly include Pokemon that weren't available in SwSh and BDSP. It would be cool if we could transfer PLA Pokemon in but I suspect that won't be a possibility given the fish out of temporal water situation that would create.
Oh and please give us an actual Safari Zone again that was cool.
