lol, hardly anyone ever comes in this particular part of the forum, so don't panic so much. I shall belatedly welcome you.
I don't think that Disney UK ever states when exactly certain titles go out of print; you normally just see stickers over them in stores before they are pulled saying "soon to return to the Disney Vault". Equally, they don't go all out with announcing things quite the same way as Disney does in the US, and it would probably be advisable to just look at their website every so often, or look at the US release schedule (as reported on UD) for clues.
I know for certain that Beauty and the Beast
is coming on 1/11 (at least on Blu-Ray), and The Princess and the Frog
will be out in just over a week. Fantasia
should also presumably come out, as should this summer's main releases (Toy Story 3, Prince of Persia
etc). The Black Cauldron
may also be getting rereleased on DVD as it is in the US, as Amazon has the old disc listed as out of print and has a new special edition tentatively scheduled. Beyond that, The Lion King
should be out in 2011, and perhaps also Alice in Wonderland
(the 1951 animated classic), most likely followed by a series of obvious classics.
