Following last week's revelation that DS Lite will begin shipping in pink later this month (in Japan) comes rumor that the upcoming Pokemon Pearl/Diamond game will usher in two additional colors.
According to an ad scanned from a Japanese publication, 'pearl' (even lighter blue) and 'diamond' (gold tinted) colored DS Lite models will be manufactured to celebrate the release of the new Pokemon titles -- no word yet on a game-bundled package. For now, expect availability to be limited to Japan.
Update: According to TotalPokemon, via Go Nintendo, the scan is a fake. [Thanks Spuky & vidGuy]
