Since this involves a topic regarding one of the GB pokemon games, this goes in the Metal/Color Generation forum.

And regarding this topic; I see no real reason for this unless they think they can still make money off of the Pikachu image alone. The actual major difference between Red/Blue and Yellow was not, in fact, the Pikachu factor, but the sprites were far improved and based off of the anime versions of the pokemon. With R/S/E/FR/LG, all the sprites are on equal footing and have no room to improve because of the limitations of the Game Boy Advance. This being said, a Yellow remake would not be useful on the DS as it would a) only serve to steal some of D/P's thunder, and b) be superfluous because of the same graphical equality, as it is likely the DS is either going to switch to stadium-style or non-sprite (i.e. scanned Sugimori art) style images for the pokemon. So...I think Yellow's time is over as far as the chances of its reincarnation are concerned.
