Dam that's an exhaustive release, not masses of stuff that hasn't been around before but the majority of the professionally recorded content that's around which will hopefully have been handled better than previously.
I believe each individual "year" sub package will be sold separately next year so its only the bonus one and the single vinyl re presses that are exclusive to the box. That will I'd guess please a lot of people, Barret fans only need to get the first one and casual Floyd fans perhaps drawn to the 69 and 70 sets with the Man/Journey and Zabriskie outtakes.
I'm actually plesently surprised how appealing it is to me given that most of it is not previously uncirculated, I spose because almost all of my unoffical Floyd stuff is audience recordings from the 70's which aren't featured. I'v never been much of a fan of unofficial video footage as its generally not delt with that well, hopefully this release improves that.
