I concur with the parent. I recently purchased and read through all four of his most popular novels: Elantris and the Mistborn Trilogy. Sanderson's default writing style is actually shorter and less descriptive... but then for first books you don't always get the luxury of killing an entire forest to describe a bedroom.
That said I have read the annotations for most of his books, Brandon's blog posts regarding his writing (cruise to his website and read up if your remotely interested) and the entire WoT series again. I have decided that with the amount of information Jordan left behind (plot) a writer of Sanderson's talent can pull it off. Sanderson has a much shorter paragraph length on average and his stories had great potential plot wise, he just chose to keep the stories shorter, though he has the vision of the grand epic. The real challenge will be nailing the details and tying up all of the plot threads on a coherent manner. The writing style, I think, Sanderson probably fell into after a few months of writing. Since Sanderson has already managed reasonably complex plots and seems to be keeping it all together (based on his blog posts) I hold high hopes for the completion of this series.
This is a series I started reading in early high school and have treasured to this day. Some books are better than others, but this series is THE epic fantasy story of the last 20 years. It is more of a brute force presence in the fantasy fiction world than something someone did decades ago like Tolkien. Jordan has defined an entire decade of writers and readers that have had to come to terms with his stories when they contemplate the fantasy epic. When an author sits down and thinks of a plot and story for a fantasy epic it is, in my opinion, Tolkien and Jordan that you struggle with: how do you do something different? How do you spin threads of a story of epic length while making the same old good triumphs of evil (epicly!) enjoyable? There are a lot of other great writers in the epic fantasy space and I don't mean to reduce it to the two most well known.... but they are where they are for a reason.
Anyhow... my rambling is done. I highly recommend Elantris and or the Mistborn trilogy. Though I suspect that most of us that have been eagerly waiting have already begun studying up on the man to finish up Jordan's legacy.
