Well, my case arrived today. Unless you put importance on picture restoration and Sir Roger Moore commentaries (he's recorded an all-new, all-solo commentary for each of his films! That's a lot of Sir Roger!), the Ultimate Editions probably won't offer you much over the previous editions.
Annoyingly,
Die Another Day is a huge
downgrade from the previous UK release supplement wise. Not only is the 70 minute "making of" missing, but the Madonna music video seems to be as well (and, once again annoying the packaging claims that the content previously only available on the UK release is "never before released on DVD"). It's no biggie though, as I still will keep the UK
Die Another Day 2-Disc release.
I've not had time to explore the discs yet, bar a quick flick through the menus on a single disc. Very good they are too (as you would expect - there's been a heck of a lot of time and effort put into them) but sadly the transitions are long and you cannot skip them. I can see this becoming irritating in the near future.
Pics (from my cheap and unexceptional digital camera):

The packaging. The case is packedged well and even includes moisture absorbing crystals in paper satchels.

The open case. All the discs are still shrink wrapped. The inside top of the case holds a paper sleeve which includes a certificate and 10 theatrical poster reproduction cards.

Each disc comes with a slipcover! Just in case the attache case isn't protection enough! Each disc also comes with an 8-page booklet, similar to the ones available on the previous Special Edition releases.

In conclusion. While I'm happy with the new set, I think I'll still keep my older UK Limited Edition Tin set. People who already have the previous releases probably won't find anything on the new releases to make it worth an upgrade. They're probably for Bond fans only.
