"The Essential Collection, which was released in Germany and Austria only in May, will be released in the rest of the world on September 3, 2012. This collection of ABBA hits and other classic tracks comes in three different configurations: a double-CD, a DVD, and a Limited Edition package featuring the two CDs, the DVD and an illustrated 28-page booklet. The DVD features all official ABBA promo clips in remastered form, including two previously unreleased videos: ‘Conociéndome, Conociéndote’ and ‘Gracias Por La Música’ (Spanish versions of ‘Knowing Me, Knowing You’ and ‘Thank You For The Music’, respectively)." - ABBAsite
I'm really looking forward to this new compilation album and I hope I'll be able to get it. :)
