As you may already know Nintendo are planning a service similar to Wiiware on Nintendo DS once the new DSi modell launches. One of the first DSware titles will be a new Wario Ware game (titles Utsusu! Made in Wario in Japan). The game will take advantage of the built in camera as you will play the super short mini-games using your silhouette.
It was recently revealed that Nintendo DSi will launch during or after next summer in Europe and the United States.
