Please don't make it a Gen I remake. They'd be missing the perfect opportunity of releasing it on February 2016 to tie in with the 20th anniversary of the Japan releases.
I'd rather get a year of nothing but decent spin-offs instead of rushed yearly releases, pseudo freemium games and micro transactions...
Why don't they learn from our friendly neighborhood Ame and release stuff only when it's totally ready?
I heard a rumour about Gen 7 being based on South East Asia and releasing the game on handhelds and Wii U. There's a lot of parts of the world that have the potential to turn into GOAT regions.
Difficulty modes? I'm in. I don't know if it's potentially hard to implement, but it could be greatly accepted by a lot of people. It could be something like this:
-Poké/Kid/Rookie/Youngster/Easy Mode: X/Y Style, 3 Pokémon at most, some of them don't even have 4 moves. Could even be underleveled.
-Great/Gym Leader/Intermediate/Novice/Normal Mode: Something like BW2 Challenge Mode. One extra 'mon, some of them have held items (but not full competitive ones, only things like sitrus berries).
-Ultra/E4/Expert/Hard Mode: Possibly full teams, held items for half of the team, decent movesets, a little bit of overleveling.
-Master/Champion/Lunatic/Pokémon Master/Very Hard Mode: Something like Drayano's hacks. Full team, full items, best movesets posible, overlevelings that could make Audino killing sprees legal.
