We got word from badam that Nintendo's DS Download Station website has been updated and now shows a "Series 1 Line-Up" and "Series 2 Line-Up". For you curious folks out there, the two-series breakdown is not really a mystery. It just means that if you want to download certain games, you'd have to go to appropriate participating game stores.

The Series 1 Line-Up includes Brain Age: Train Your Brain in Minutes a Day!, Mario Kart DS, True Swing Golf, Tetris DS, Meteos, Metroid Prime Hunters Movies, and Pokemon Trozei. These titles are available for download exclusively at Target stores.

The Series Two Line-Up is available at GameStop, Game Crazy, and Best Buy stores. Titles in this line-up includes Brain Age: Train Your Brain in Minutes a Day!, Magnetica, Over the Hedge Movie. Tetris DS, X-Men: The Official Game Movie, Metroid Prime Hunters, and Big Brain Academy. These titles will also be available at Wal-Mart and Toys 'R' Us stores.
