In addition to last night's Dr. Mario and Pokemon Farm announcements, Nintendo will also release Maruboushikaku and Minna de Puzzloop (known stateside as Magnetica). Maruboushikaku involves three screens displayed, each with its own pattern (circle-, line- and square-based). We don't yet know the objective of the game, but your actions in one window will affect the other two.
The game previously known as Pokemon Farm is officially titled Pokemon Bokujou Channel (Pokemon Ranch Channel) and will let you take your Miis to the ranch to take pictures of your pokemon and send your friends. Pokemon management was mentioned, but no information on whether you level up your characters in the channel.
Dr. Mario & Saikin Bokumetsu (or "bacteria extermination") will also feature your Mii characters in-game and has options for online multiplayer. Saikin Bokumesu is a minigame from the Japanese Brain Age 2 and will feature four-player online co-op. IGN has a handful of pictures from the game.
Star Soldier R, Final Fantasy Crystal Chronicles: The Young King and the Promised Land and Moji Pittan Wii were also announced last night. Wii Ware is coming to Japanese consoles in March.
