the end of an era? Sacagawea's are done in this incarnation and Lincolns are going where?

Just ordered my 2008 Sac's and was wondering again, is this the last year for that set? As of next year, the reverse of the Sac will be the rotating Native American themes. That constitutes a new type or at the very least, at least some division in the Sac collections. I think? Also, next year is the commen Lincoln's. Are these going to be the end of a period? With all the talk of changing the cent, or the elimination of the cent, what better time to accomplish this than after the commenmorative are done. Personally, I am not in favor of the elimination of the cent, but would like to see a redo, and a new theme. How about bringing back a Lady Liberty of some type? Or even a new idea not yet done on our coinage?
