The rumor going around various LEGO sites right now is that next year will see a new version of the UCS X-wing. It's a divisive issue, as some think that a new version would devalue the original, and that the UCS series should be about collectibles, while others (including those who never got the chance to get the original) would welcome a new version. Another argument is that LEGO should continue making unique UCS's and not start to redo what has come before.
Personally, I welcome a new UCS X-wing, and would love to see what LEGO could do with it 12 years after the original.
