Holy Cr@p, Batman! I just read the first page... haven't visited the forums in a while and other than Scott & David, I think everyone elses "Dream" ROTJ wave consists of all resculpts! Don't get me wrong... I think all listed desperately need a resculpt, well at least most of them anyway. But any dream wave of mine would include some all new figures, too. I mean, there are plenty left that never been made! Ok, now that I got that off my chest, I can go back and start reading page two! 
Excellent point. I think the reason we've got lists that are chock full of resculpt requests is due to a few factors.
-First, so many characters have already been made into figures. We're getting to a point in the line where we're starting to run out of all new characters that have never been made into figures. I think Hasbro might be holding off to a degree just to have some characters in reserve for the future. Perhaps this mindset has unconciously made it's way into the collecting community? But if we were to start talking about Jabba's palace denizens who have yet to be made, the list of named characters with reasonable screen time is dwindling.
-Scene specific versions of characters are another factor. People want good versions of X character in Y setting. And I think to some that might translate as a resculpt.
-The improving figure aesthetic. Let's face it: a figure like the Weequay which originally came out around 1997 looks pretty crude next to a 2007 figure. Between the sculpt and the articulation, the 10 year old sculpt looks pretty bad in comparison with current offerings, and collectors want something better for certain characters. Hasbro has found a way to get us to come back for more of the same character by improving the quality of their product.
As for my own list? It's really more of a list of what I think we would get in this wave rather than what I would want if I was planning the line. Call it pragmatism winning over idealism.
