Here in the US, both WiiSports and WiiSports: airplane are pre-ordering for $60US apiece. I think just the presence of the two titles and having people pay money for them would indicate that not only will they be separate games, but that they will also not be included with the system. The same goes for WiiOrchestra.
Im surprised to see wii:aeroplane being sold seperately. Thats why they called it wii:sports aeroplane. If it wasn't part of the wii sports game, why would they call it 'wii sports'.
If they have decided to sell aeroplane as a seperate game then they must have more depth to it.
