Did you forget that Ninty already made a new region for Pokemon Black/White. And you could fit all the Regions on the DS (or 3DS ). It's all about memory size. As far as I know there are no DS games that use more then 1gb of space(Probably less) and if they can fit 32gb on a "Micro" SD card I bet they could fit 32gb on a DS cartridge no problem. It would be the most Epic and Time consuming game EVER. Another thing they could do is make you pay to unlock certain Regions or something to satisfy they're money need. I know that'd suck but hey, if they don't see enough money worth(or payoff) in something no companies are EVER do something that doesn't get them payed in some way(unless they've got horrible business seance). It'd be sweet. And Also Make a WII game that would unlock certain special features or extra Areas would be awesome.
PS: I got a ROM hack for Platinum that let's you catch all 493 Pokemon in game without any trading. Even Pokemon that require Trading to Evolve were changed so that they Evolve like other Pokemon. It's called Bloody Platinum and it can even use your normal Platinum Save File. I won't tell you where to get it or a ROM of Platinum but remember you have to Own Platinum LEGIT before you use the ROM.
Okay first off that would be way epic and if they wanted they could keep the pokewalker feature still and alsoitd be like $70 or $80 for it but still it would be worth it. also they could add B&W's regions (Black and white) into the game with new ones and new pokemon. All in all it would either be the previous price or higher. now that may suck but it would be AWESOME!
And jap whats a ROM hack and how do u do it? t(this may seem like a lil much but) could u also pm me where to find it? cuz i got the original platinum and it sounds cool.
Well, im probably the only person on this website that doesn't know how to use a ROM, how to download PokeSav and how to make AR Ds/ Dsi codes. Me so sad:
