The first DSi Ware titles, downloadable software for Nintendo's currently Japan-only handheld, have been announced.  Included is Chotto Dr. Mario, yet another rendition of the Nintendo action puzzler.  The game features classic single player and Vs. COM modes.  Also upcoming is Utsusu Made in Wario, a new Wario Ware game, which in true Wario Ware fashion, features gameplay that revolves around the latest Nintendo technology.  In this case, at least one of the DSi's built in cameras is used to control the microgames.  Both games launch with the service on December 24th and will cost 500 points.
