Wow.
First - I didn't expect Pinkie-Dawn to be so distressingly bitter and spiteful about this announcement, but second, I DID expect you to be. Apparently I was wrong on both counts. Though I would say that describing yourself as a "doubter" is a bit disingenuous. I can't even count how many times over the years I've been reading through a thread here on pretty much any topic, only to see you show up to post something about how much you hate RSE.
But anyway - you're certainly not the only one who expects something other than remakes. And I think it's definitely the most likely scenario, not simply because of mega-evos, but because of all the new things that have been introduced since RSE. They're certainly going to want to include at least some of those features, and it'll be awkward at best to just shoehorn them into the original stories, so it's far more likely that they'll tell entirely new stories and just base them in Hoenn.
Well they've announced the games, what do you expect me to do? Cry? I don't like the idea, but I still think they could make it something good (and way better than RSE was, for example).
If they fix the pet peeves I have with Hoenn...
1) Bad Pokémon roster with bad movepools.
2) Trumpets everywhere.
3) Navigation of water routes is very confusing.
4) Pointless backtracking in some areas.
5) Enemies (especially Elite Four) with uninspired rosters.
It might even be a good game.
What I DON'T want them to do is to remake them strictly like they did with FRLG and HGSS (to an extent). FRLG sucked balls because of that, and I hated the Sevii Islands as well. And HGSS, despite being a good game, doesn't fix several things that were wrong in GSC. The biggest one is that the level curve is too low and the rosters were mostly the same as GSC. So the game became too easy after a certain point. What they could've done is sacrifice roaming freedom by blocking Mahogany until you were done with Olivine. This way, the levels could be higher in the parts after Olivine.
But a strict remake with everything unchanged? No thanks.
The fact they didn't go with the obvious Magma Ruby/Aqua Sapphire makes me think that maybe, just maybe, there won't be a sign of Team Aqua/Magma in the game. It depends on when the game takes place. If it's after 5th gen, the teams have disbanded and don't exist anymore. Maybe they could reform, though.
