I have one question, how come lego doesnt re release any sets any more, they used to re release lots of sets in the 'old days'. my examples are the x wing I mean they have made like 4 different sets! 3 re-released. the y wing also, and the a wing
Jar-Jar will die...,Jar-Jar will die...,Jar-Jar will die...,Jar-Jar will die..., DIE Jar-Jar Binks!!!!!
Well, at this point they prefer to do re-designs and updates as opposed to just re-releasing an older model. An example would be the 4502 X-wing (one with the Yoda Hut) which then became the 6212 X-wing (Hoth theme, with Wedge). Even though it was the same ship it was technically a re-design. The original Y-wing wasn't seen as up to snuff so it was replaced with the new version in 2007.
Its just the desire to have something new and exciting out there while maintaining consisent releases of familiar sets. 2008 and 2009 are heavily themed for Clone Wars though so that may be why you haven't seen new versions of some of the classic fighters in the last year or two.
