I know this isn't really the place to talk about this, but I doubt more Gen I remakes will come anytime soon. Not only has Kanto been milked out several times already between FRLG and the Johto games
Kanto in Gen 1 =/ Kanto in Gen 2. That's like saying BW and B2W2 are the same games just because they both have Unova. The difference may not matter much to people who only care about gameplay/mechanics (who, let's be honest, probably wouldn't care if Kanto or Johto were ever seen or heard from again, as they aren't attached to any particular setting or characters), but to those of us who
do value stories and continuity, it
does matter. (And, we're just as much a part of the fandom as "metagame"-focused people, like it or not.)
Besides, it's been a very long time since we last saw Gen 1. Even if you just look at Kanto, itself, 5-6 years ago isn't all
that recent.
HGSS are old enough to be out of print, after all, and will probably cost you as much as
$125.00, more than three times as much as a new copy of
OmegaRuby. Oh, you want to play the
original GSC? Get ready to plop down
$200 for a game that you will probably need to replace the cartridge battery for and can't be played on anything newer than the obsolete, out-of-production GBA SP.
But, at least, GSC's remakes can still be played on a 3DS and are still decently "modern," graphically and mechanically. With RBY, you're stuck with the glitchy, broken originals that are worth anywhere from
$300 to
$1200(!) and their outdated, mediocre enhanced ports (FRLG don't deserve to be called remakes), which are similarly
worth a fortune, all of which need obsolete hardware to even play.
If you like Gen 1, this is what you're stuck with. No P/S Split, no Day/Night, no 3D graphics, not even any Pokémon beyond #151, and an empty wallet.
