Nintendo has revealed that there are currently about 100 WiiWare titles in various stages of development.

From an interview posted on IGN:

"Our plan is to make new WiiWare games available on Mondays, as we do with Virtual Console titles."

And:

"Developers have the ability to utilize the same Wii features for WiiWare games as they do for disc-based games, including Wi-Fi Connection, WiiConnect24 and variety of controllers and peripherals. What is important is providing developers the freedom to use the features that are most valuable to express the characteristics of their game. Regarding the use of Miis, Mii characters are included in games like TV Show King and Dr. Mario Rx. "

The idea is to give developers as much freedom as possible to develop new WiiWare games in various sizes and obviously worth various point values.

Currently there are 24 WiiWare games on the Nintendo site.
