Haven't seen this mentioned, but West Wing Season 4 has a new style packaging than the previous 3 seasons. Instead of the four-disc foldout, it is now the "book style" six panel case, sort of like Star Trek: DS9. And yes I said six panel, because hallelujah, there are no flippers in the set. Six single-sided, (presumably) dual-layered discs. I really disliked the flippers, and only wish they had done the previous three seasons this way. The outer case is like the others, and they look good onthe shelf together, although S4 is a tad thicker than the previous boxes. Can't wait to tear through this season like the others.
