Re-packaged singles album

I'm not sure what the point of this is, but someone has decided to reissue the band's 2004 singles compilation, this time as a joint-package. Initially both the DVD (with the videos) and the CD (songs only) were issued separately. The bit I don't understand is why reissue an item that is already on the shelves? The set is out on December 3: 'This Is Music: The Singles 92-98'.

Here's the tracklisting for CD:
This Is Music, Slide Away, Lucky Man, History, She's A Superstar, On Your Own, Blue, Sonnet, All In The Mind, The Drugs Don't Work, Gravity Grave, Bitter Sweet Symphony, This Could Be My Moment, Monte Carlo

Here's the DVD tracklisting:
This Is Music, Slide Away, Lucky Man, History, She's A Superstar, On Your Own, Blue, Sonnet, All In The Mind, The Drugs Don't Work, Gravity Grave, Bitter Sweet Symphony, Lucky Man (US Version), This Could Be My Moment, Monte Carlo
