Brandon Sanderson explains how the last book of the Wheel of Time series became a 800,000(or so)-word trilogy. And all I can think is: Man, I have a hard enough time getting to 100,000 words. That man is just plain nuts. But I expect Wheel of Time fans will appreciate the extra effort in the end. Here’s the actual Tor press release about it, by the way.
Also, before anyone kvetches here about the last book being split up just for the money, do yourself a favor (and keep yourself from looking like an ass) by reading what Brandon has to say about it. Seriously.
