The Johto region game has so far only been G/S/C, although a supposed "remake" of it was posted in the past week which has now been confirmed as fake.
If they were to make a Johto remake, I'm sure many fans would buy it and thus Nintendo making lots of money again seeing as Johto is probably the majority's favourite.
As for a release, it's kind of likely but there won't be anything on it for awhile at least until D/P commotion dies down.
