Pokemon grey version?

I'd think they would make a Pokemon Grey version, but there really is no way to tell as of now. I've heard that GameFreak (guys that make Pokemon games) would make a Pokemon Grey that would go more in-depth on N's past and his real name and so forth, and that Kyurem would logically be the box art and mascot legendary for Pokemon Grey. However with the Nintendo 3DS out now, by the time a Pokemon Grey would be released (estimates seem to be late 2012 for Japan and 2013 for the US) the Nintendo DS would be considered pretty much obsolete. Black and White are obviously on the Nintendo DS, but by late 2012 the Nintendo DS likely won't be gaining any new games because the Nintendo 3DS will of taken over for handhelds. With that said, for GameFreak to make a Pokemon Grey they would either have to release it for the Nintendo DS like Black and White were, or release it for the Nintendo 3DS. In both cases there is a problem because Nintendo may not want anymore Nintendo DS game additions that relatively far into the future when they hope to have the Nintendo 3DS take over. But for GameFreak to make Pokemon Grey for the Nintendo 3DS wouldn't make sense either because it would not match the graphical aspects as Black and White. GameFreak would have to redo all of graphics for all the characters and objects from Black and White, which would be financially a waste of time. GameFreak would be better suited making another Pokemon series (or the rumored remakes of Ruby/Sapphire) for the Nintendo 3DS if they really want to put that much time and effort into another Pokemon game. So there is rumors/evidence for both sides of the Pokemon Grey debate, but in my opinion unless it were to be released within a time frame sooner than the one estimated then there will not be a Pokemon Grey. It just so happened to come up at a bad time with the transition of Nintendo handhelds.
