Question about R2 US release

[cryingcat613.livejournal.com]

So I was looking at R2, Part 1 on amazon (to make sure the release date hadn't changed again) when I saw that not only were there the two original releases (with Lelouch on the cover), but there were two other R2, Part 1s for sale with Suzaku on the cover. What, if any, are the differences between them, or is it just Bandai trying to make more money with four different releases?

Lelouch cover
Suzaku cover

All I can tell is that the Suzaku one won't be released until 10/6...
