I read somewhere that the new ones have a little lag in release on the Movie Club site. Also, here is a link to Disney movies that are currently out of print:

-Snow White will not be released again until 2012 (it was discontinued Jan of 2002 and is on 10 year "moratorium"- the fancy name for the Disney vault).
-Little Mermaid's Platinum edition will probably be released October of 2006, the limited issue was discontinued in Jan of 2000.
-Sleeping Beauty's special edition was discontinued Jan of 2004. No word on a platinum edition coming out.
-Incredibles- new and will probably be on the site in a few weeks (?)
Disney likes to release and discontinue dvds at different times.
The logic is- if you know it won't be sold for 10 more years (or until a date TBA), you're more apt to buy it even if it isn't your fav movie.
Cinderella is the next DVD up for release and will be available in stores October of 2005.
Sorry! Check out ebay if you want these- but you'll notice sealed copies of Snow White (a used one just went for $40) and Beauty and the Beast especially are going for HUGE amounts (both are currently on 10 yr moratorium). I saw the two go off together for $100 the other day!! There are also TONS of bootlegs out there so if you go the ebay route, be VERY careful.
I have to confess- I just spent quite a bit of money on a sealed Peter Pan dvd on ebay just last night. I just couldn't wait until it comes out again!!
