I do see the issue, and it's a good question. I agree only that PG Music has not yet made the answer clear.

I have asked if there is anything that I can no longer get if I didn't buy that particular bonus pak along the way. Just because it says Unreleased here, does not imply it will be added to the regular release in the future. I really hope your interpretation is correct, but I don't think we know yet.

And by the way, yes, MusicVillian, no other program I've seen comes close by an order of magnitude to the size of BIAB. That is certainly the case from 2008 on, with the introduction of RealTracks (and maybe even a year before, with RealDrums). Before 2007, BIAB is still the clear winner for the number of files, if not the largest storage size of the files taken together.
