Liz, I don't know that going from 6mp to 8mp is a big improvement in a lot of cases. I've made 16x24 prints with my 6mp and been quite happy.
Other things might make more sense though - less weight and could be better at high ISO speeds if you use them. Canon has done an excellent job with high ISO's and I'm sure this camera will be no exception. And then there's the fun of new equipment too...![]()
