I'm thinking that Wii Sports 2 will include enchaced versions of the events from Wii Sports 1. That way Nintendo can bundle consoles with the new version and Motion+.
I also think Motion+ will start being bundled with new remotes.
I only think this because IMO it would be the best way to make Motion+ a standard peripheral for the system.
