Breaking news from Yahoo.co.jp (it's all in Japanese, don't waste your time):

We learned on the 7th that "Pocket Monsters Gold and Silver," the second entry in the popular RPG series, originally released on the Gameboy system in November of 1999, will be remade for the Nintendo DS this autumn under the titles "Heart Gold" and "Soul Silver." New elements will be added in this tenth anniversary return to the Johto Region.

A continuation of the original series (Pocket Monsters Red, Green, Blue, and Pikachu), Gold and Silver recorded remarkable sales of 23,000,000 copies worldwide. It introduced monsters that hadn't appeared in the gameboy games, along with various new features.

Red and Green, the first games of the Pokemon series, were remade for the Gameboy Advance in 2004 as "Fire Red and Leaf Green," making this the second set of remakes. Just as with Red and Green's transition from Gameboy to Gameboy Advance, the Gold and Silver games will likely receive a graphical and sound update in the transition to DS. Details will be released on the official site shortly.

I know at least one editor who is sure to be thrilled by this news... and five bucks says he's the first one to post a reply in the comments section.

More as it breaks.
