I totally agree, Ben.
Unfortunately, BVHE hasn't been putting as much effort into recent DVD releases as they could be. There has been some speculation over on the Ultimate Disney forums that they could be holding back on some bonus features to encourage people to double dip (or triple, or quadruple) for future Blue Ray releases, but I really hope this isn't the reason - especially since many consumers will likely stick with standard DVD unless it becomes obsolete.
But the sense that they've just been "mailing in" most of the the standard-def DVD releases seems to have really begun in late 2005, when the out of print 2-disc Tarzan collectors edition was advertised as a 2-disc reissue, but arrived in stores only as a one disc, which seems to have been intended as the first disc of a two disc set, as it had less bonus features than many one-disc releases (no making of or art gallery!).
Also, around the same time, Emperors New Groove got reissued only as a one disc leaving most of the meaty bonus features on the OOP 2-disc CE "in the vault".
Around 2004 they put out solid 2-disc sets for Alice In Wonderland, Pocahontas, and Mulan, but every reissue since then of a catalog "animated classic" (other than the "Platinum" titles) has been one disc affairs that offer maybe a slight improvement over the original release, but hardly getting the deluxe treatment they deserve.
Also, the new animated films from Feature Animation are arriving on DVD only as single disc releases with no alternate 2-disc version targeted at "collectors".
Even the last 2 Pixar DVDs (Cars and Ratatouille) were only available as a single disc, far skimpier than the packed 2-disc CE's the previous Pixar films were so acclaimed for.
Lastly, there are still a ton of classic live action Walt-era films and anthology episodes yet to see the light of day on DVD.
I really hope they turn things around.
