Great write up and it's nice to see what we're getting in context with what there is available.
To one point:
QuoteWhy they didn't just make a decent box set with all available recordings and complete shows remains a mystery.
I'm certain the answer comes down to the budget for the project and the desired price point. Even though it's far from complete, five discs is still a lot of content. I'm sure the record company also sees $60 as a tipping point. That price and volume of content will appeal to a wider array of buyers. I'm sure they're correct to believe that if they had pushed the price up to $100 and included 8 or 10 discs the sales would have seen a sharp drop.
