This has to be the stupidest thing we've read from GDC so far. According to this, Nintendo has said that 100 games will be ready for WiiWare's US launch on May 12, but will only be released a few at a time, in the same way as the Virtual Console Service.
So, Nintendo, what you're saying is that you're going to make a few games a week available on WiiWare, with a few available at launch. Glad we got that sorted out.
Other WiiWare information at that link says that not anyone can get games up on the service (dur) and an apparent confirmation that demos won't be made available at all.
