I thought about X-Wing Luke, but for whatever reason I have a great deal of fondness for that figure, it really impressed me when it came out (what? 12 years ago??) If they resculpted it I would probably have a hard time upgrading just because of the nostalgia factor.
The same thing happened to me when they did Bespin Han...I had a real hard time giving up POTJ Bespin Han (OK, so I didn't even give him up, he's still on a shelf because I still love that figure, as outdated as the sculpt may be.)
