Uuh... that would be sweet... transportation by train,airplane,ships to different regions... It would be possible if they want it... but they mostly want people to really trade with each other...
i'm going to miss the HG/SS feature... pokemon walking behind the trainer...
Hm... Wonder if they're going to make Ruby/Sapphire...
-------
Well it would be nice if they make a totally new pokemon game...
Play as a new character... not the manga character.. Gold,Red,Pearl... but new customizable character... hair,clothes,face and such...
Wider range of starter... not confine to the three fire/leaf/water starter...
But that would be like an mmo...

a man can dream.. a man can dream..
