Brandon Sanderson’s plan for Mistborn era 3 is exciting and could indicate the possibility of it topping the original trilogy. Out of the seven current Mistborn books, the original three are still commonly considered the best, along with being the author’s most widely read work. That’s not to put down the Wax & Wayne series, which did a fantastic job at developing the world of Scadrial after a massive time jump, but Sanderson found lightning in a bottle with the first three novels.
