I just found out about this about an hour ago myself. I took a look at the box set. Tempted to get it for the Mrs. for a Christmas gift. I am a fan of Queen, she is a massive fan. The Miracle though - I never thought it was the greatest record. Solid, for sure. But the hype looked a little overdone.
The other thing I am trying to figure out is whether the box is worth it, at least for my wife. I preordered at Amazon, and then cancelled, waffling a bit. It's a tad pricey at 180 for what I know that she personally would get out of it. So I may opt for the two CD release. She's not a huge vinyl collector, and while I know she would enjoy the book, the BluRay, etc., all the extras aren't something she'd really sit and pour over, I don't think.
Been playing The Miracle and The Game this morning. Next up, Innuendo...
