I guess it's safe to assume that those of us that want the vinyl will also have to buy the other formats to get the unreleased bits and bobs. To be honest I would rather have had the box set than having to repurchase CDs for each album to get the "new" stuff. I don't particularly want more copies of those CDs on my shelves, particularly if the mastering isn't up to snuff (read: more compressed). Also, I'm very attached to my original copies, so wouldn't get rid of them regardless.
What I'm most keen to discover is how the mastering has been done on the LPs of Afterglow and TOE. TOE may be a lost cause, not sure, but I can dream of a nice dynamic mastering. Can't sound much worse than my ATO copy, surely?
Meanwhile, my wallet is hoping that the first four album reissues don't sound as good as the original LPs!
