I'll be ordering the trilogy from Amazon shortly as well. I like that you can buy the trilogy as one ebook and I wish they would do this more often....specifically a lot of the trilogies of Star Wars novels
Or the Barque Cycle...
I just finished book 10 of the Wheel of Time and I believe Sanderson took over on book 12. Looking just at the star reviews on Amazon, it seems he did right by the rest of the series.
I'm also interested in his Stormlight Archives but just as I didn't start the Wheel of Time until recently....I will probably wait for book 7 or 8 of 10 to come out before I jump in.
