Well really, to include the unreleased material they may have and be able to, it would be a big box, studio or live, and I think they feel they are better served in many ways by making a series of single releases (that I think must sell alright, more perhaps than a big box might). This is just my guessing from the way they are doing things, and the amount of alternates they are including with each new reissue, etc. I'm going to go outside my normal likes here and say at this point I'm wishing they just continue the single releases; I've bought all the released stuff several times, and don't relish rebuying yet again most of it to get what rare stuff they might include in a box. . . . They're doing a good job with the single releases and frankly I'm surprised to see so many more on the horizon so soon!
