I wouldn't like it very much because if they make R/S/E remakes for the 3DS they would be quite expensive and a lot of people don't own a 3DS . But for me it's kind of obvious that it will happen
1 Gen - Game boy
2 Gen - Game boy color
3 Gen -GBA + remakes of the 1 Gen
4 Gen - NDS and NDS lite + remakes of the 2 Gen
So it has to be
5 Gen - 3DS + remakes of the 3 Gen
Every generation has an exclusive game for the current brand new device,3DS is the device for the 5th Gen. And after the 3rd Gen they make a remake game of a past Gen.
