Yes, I was a bit bummed about this as well.
(Just set up Band in A Box, and am realizing everything didn't mean everything.)
Well, I knew that already because in the comparison page you can see you have to upgrade from everything to get the Wave files.

But the real bummer is that there is no way to really know what I do or don't have (as far as I can tell by looking through the site for a while) - There is no explanation page as to what really comes with the everything pak, etc.

Why is it so difficult to have a page listing what comes with what - why demos will be greyed out until you buy this or that, etc. If anyone knows where this page is, (I'm hoping,) please correct me.

On the other hand, I'd buy it again in a second. It's a very cool product.
