5th gen plans

[Sengir]

However, I honestly think that R/S/E remakes will be made

That's way more unlikely than even Grey. They'd have to program from the ground up a Pokemon RSE remake for a finished console instead of modifying BW, which is really impractical.

And Tyvon: the DS may have a year left in it, but that's for 3rd parties. Nintendo always does a last major 1st party game before being done with it. Pokemon Black/White (or the Pokemon Typing game in Japan) is that game.
