It smacks so much of "cheap cash-in"...kind of reminds me of the LotR, then LotR extended thing. If anything, they should be released at the same time.
NewLine announced the 4-disc set long before the movie was even out of theaters. People knew good and well that there would be a better set coming along, so I have absolutely zero sympathy for anyone who bought the bare-bones, 2-disc set and then felt compelled to shell out more money for the 4-discs.
But that's off-topic...
On a side note, many of Bob Dylan's albums will be re-engineered to take advantage of 5.1 surround sound. Now that's cool.
This is very cool. Also, REM's Reveal and Automatic will be getting a similar remastered treatment.
If there's one album that's in need of an updated sound quality, it's ACHTUNG BABY!!!!!
