The live DVD due later this year is of the Milton Keynes show called "Queen On Fire at the Bowl." I'm thinking that the article mentioned previously is mistaken and they simply wrote "CD" when they should've written "DVD" because a DVD is the ONLY thing that's been mentioned. Brian May, on his official web site
www.brianmay.com, has never mentioned a CD release, only the DVD and the work being done on the audio/video of the concert.
Having said that, I would LOVE a proper CD release of the show. Wembley was released on CD & DVD (the CD was even re-released after the DVD with matching cover art...plus a few bonus tracks.)
As for the new "Hits" CD, I believe
www.cduniverse.com has both the album cover and full tracklisting for it. The cover is exactly the same as the *original* "Greatest Hits" album as is the tracklisting except the 3 bonus tracks already mentioned (the 2 live tracks are from the Milton Keynes show and are "teasers" for the DVD. Considering that this CD is a US-only release, the Keynes DVD will be released in the US as has every other Queen DVD.) The CD is also intended to help promote the "We Will Rock You" musical because they sloppily (sp?) added the musical's logo to the album cover. Brian May has said this CD will be a limited edition.
