It's just something to attract the Christmas season shoppers.
If you already own the 2004 set, don't even bother, unless you want to spend $40 on a different box.
Now if you were foolish and bought the full frame version before and now want the Widescreen, this would be as good a time as any to redeem yourself and get a new box in the bargain! But then the Widescreen (silver package) 2004 set would still be cheaper than this new one (suggested retail price is $49.98! ... for reference Amazon.com listed the suggested retail price of the 2004 set when it first came out as $69.98, but most places sold it for $45, or as cheap as $40 back then).
Anyway, it's your money.
PS: Unfortunately, these are NOT the original editions. The content is the same as the 2004 set, except they got rid of the fourth, bonus disc.
