Using MUH patterns, this can be easily modeled.
>Red and Blue (GB) release year: 1996
>FRLG (GBA) release year: 2004
>8 years
>Gold and Silver (GBC) release year: 1999
>HGSS (DS) release year: 2009
>10 years
>Ruby and Sapphire (GBA) release year: 2002
>ORAS (3DS) release year: 2014
>12 years.
As the patterns point out, each original game and remake is separated by 2 handheld generations. At the same time, the length between each original game and its remake is increasing at a linear rate of 2 years each time. With this, we can create this projection:
>Diamond and Pearl (DS) release year: 2006
>Remakes (Handheld after 3DS) release year: 2020
>14 years.
Looks like you'll have to sit tight for a while, anon.
