I think that pokemon grey won't exist.

In the best case scenario, I could see it being released for the Wii as a straight port from DS, only with sharper graphics, no pixelated monsters.

While working on that, there could be development sharing between Wii and 3DS.

It could be a killer title to release early 2012 for the Wii.

Why are you still so butthurt that Black and White is on DS?

Why do people keep on dreaming that this type of Pokemon game will ever be released on a home console? Get over it. Pokemon = Pocket Monsters!!!

It'd be a good idea, but I'm almost 100% sure that it's not going to happen.

Whose butt hurt? I could care less whether Pokemon Black and White is on the DS or 3DS. Honestly since I own DS and pre-ordered 3DS I'm getting it either way. Infact Pokemon Grey could be Nintendo's last big game on DS in 2012, Nintendo should continue somewhat supporting the DS after 3DS launches. However I think as a gamer it would be pretty cool to see Black and White enhanced into 3D.

It'l most likely be on the 3DS. Iwata confirmed a 3DS pokemon game is in the works. Black and White also added many more 3D effects to the series. It's a no brainer. Gray will probably be released in September 2012 in Japan, March 2013 everywhere else. By then DS will be in a big decline, and a main pokemon on 3DS will drive crazy sales in the 3DS's 2nd year, beginning of it's 3rd year.

On another note, it does seem like a lot of people want to see their pokemon in 3D (not talking about the effect there), while a good portion still wants GameFreak to strictly represent them with sprites. There should be an option in the options menu to switch between them to make everyone happy. =3

I want to see them in 3D too and moving, but sticking inside the circle. 3D graphics in classic battles.

Then an augmented reality option for local VS battles  were you could put the beasts battling on a big ass stadium created on your room by augmented reality =p

I'm thinking it will be like Gold and Silver, where it can be played on the older system but it's enhanced by being played on the newer one. 

The sequel to Golden Sun: Dark Dawn is being developed for the 3DS.

EDIT: The mascot for the "Gray/Grey" Version will be Kyurem:

Yeah, I think so. It'll have really gimmicky use of 3D, though - like Pokemon Yellow with colour on GBC. They'll wanna hold on to the whole "oh, look, it's just like before" impressionn that they're trying to create with BW.
