I think two things could change their position on this: 1) Downloadable DS demos are planned for an upcoming Wii channel 2) Demos of Virtual Console games will be included on Brawl.
Depending on how those work out (either in terms of increased sales or by consumer survey response), Nintendo could change their mind. That being said, I'm surprised they won't have them at launch.
