Excerpt from Wikipedia: Greatest Hits are
video games for the North American
Sony PlayStation,
PlayStation 2,
PlayStation 3, and
PlayStation Portable consoles that have been officially re-released at a lower price by Sony. While the term "Greatest Hits" only applies to selections in
America, equivalent programs exist in
PAL territories (as "
Essentials"),
Japan and
Asia (as "
The Best") and Korea (as "
BigHit Series"). Greatest Hits titles are colloquially referred to as "red label" (or "green label" for PlayStation titles) referring to the colored band that is added to the packaging to differentiate it from regular releases (which are similarly referred to as "black label"). A game can earn this distinction if it meets certain sales criteria within two years after its release. The original versions of the game (often referred to as "black label") are often sought after as
collectables or the other label is white, which is named as
Collector's Edition, is similar to the green version, but it usually contains mainly the released games from one series.
If this is true, GT4's red label/re-release was around early 2007. As of 2007, Gran Turismo 4 has sold around 8.79 million copies. Today, there exists 11.73 million units.

2.94 million copies of GT4 have been sold since 2007. This means about 13.3% of all copies are Platinums/Greatest Hits/The Best/BigHits. To top it all off, black prints of Gran Turismo 4 are not rare at all. Greatest Hits are more valuable than black prints. Some black prints, even most can be considered collectibles. But this is not the case with Gran Turismo 4. I do not know if GT4 is out of print yet, but red labels will likely never outsell blacks.
