My post below is WRONG:
I hate to correct you, but Widescreen, you are mistaken.
Season One has been re-released by Warner on local R3 already, and based on the sealed set/listed features on the front, the NEW version (that I just saw yesterday at Astro-Mega Mall) is identical to the R1, even down to the packaging: unlike the bulky packaging of R3 Seasons 6 & 7, the just released Season 1 is 4-discs in the fold-out style.
Other than the packaging in Amaray-style cases, R3 Seasons 6 and 7 are identical in content/features to their R1 counterparts, as well.
