I'm sensing a pattern here
1st Gen RBY
2nd Gen GSC
3rd Gen remake of RBY, RSE
4th Gen remake of GSC, DPP
5th Gen potential remake of FRLG/RSE, and 5th gen stuff
Thus, you can say that 3rd gen and onwards will have remakes of (gen no. - 2)th gen.
If my speculation is correct, in a few years Nintendo will release their newest gaming device, then announce 5th generation, then 2-3 years after that, remakes of 3rd Gen.
