I would like to know if there are any specific plans for bluecurve as of yet. Although it is my favorite icon set, it could use some updating and revamping. Was the original author Garrett LeSage? Although I would not mind seeing some of the tango guidelines applied to bluecurve, it would be sad for Fedora/RedHat to ditch the bluecurve icons and replace them with Tango icons. I always thought the bluecurve icons (and other theme elements) gave Fedora a look of it's own, separating it visually from other distros. Ubuntu just developed their own icon set, but it's a little to hard on the eyes for day to day use IMO.
