The New PokeDex should separate all the Pokemon.
Kanto Dex:
1-151
National Dex:
152-251
Hoenn Dex:
252-386
Shinou/Alternate Dex:
???-???
I think that's how they should be separated.
When you go to "PokeDex",a list will appear and you can choose which Dex to see.
Most likely like the FR/LG Dex.
But FR/LG PokeDex's was boring,seeing as you couldn't scroll down.
But,when you access the which Dex you want to see,you can scroll down and see all the Pokemon,like R/S/E PokeDex.
I was thinking that when you first start the Game,you get the Alternate Dex first and you see all the Pokemon that are available in Shinou including Kanto/Johto/Hoenn Pokemon.
Shinou Dex only gives the list of Shinou Pokemon.
National Dex only gives a list of Johto Pokemon only.
The reason I putted National Dex was becuase the Johto Region doesn't exist anymore in the 3rd Generation Games.
Except for Celio that says that Bill lives in Goldenrod City,but that is just a little addition in FR/LG to tell that he really lives there.
You all know how the Kanto Dex,Hoenn Dex's work.
Kanto Dex,Kanto Pokemon only.
Hoenn Dex,Hoenn Pokemon only.
Most likely,we may get 300+ new Pokemon for D/P.
