Yes I too hate endless re-releases of films. However, the James Bond Ultimate Edition set is really worth it for people (like me, who didn't snap the older DVDs) to buy this set if they so wish.
The reasons are clear; the new restoration process by the world's leading frame by frame restorer apparently makes the films look much more recent. They have all remastered DTS tracks, which will upset those who like mono, but will delight DTS lovers - myself one of them.
The new extras are probably not that much more exclusive than we had before, but the fact that they are including the old extras means you're not missing anything. Also, Licence To Kill, Goldeneye and Tommorow Never Dies are uncut, meaning we get to see the proper violence that was cut by the UK censors. I think OHMSS is also going to be the correct print (which must mean the old DVD was the wrong print - but I'm not sure).
I know people who purchased the old set will be annoyed, but for those who didn't this is probably the best time to get the Bond series - the obvious HD release will be amazingly expensive and will not increase the levels of picture quality to justify paying 5x as much. So, I think this is the best release to get for the next few years. The purists and the current DVD owners will be horrified, but hey - don't they know Hollywood by now?
