From the official website:
New York Times #1 best-selling author Robert Jordan passed away on Sunday September 16th at 2:45 PM EST. His passing was announced by his cousin Wilson on his official blog, hosted here.
I've been reading Robert Jordan's novels for a long time and have all of the available "Wheel of Time" books featured prominently on my bookshelves at home. His fantasy writings were complex and emotional, weaving together the lives of many characters through dark and trying times. He died before completing the 12th and final volume of the "Wheel of Time" series although currently it is believed that enough of the final volume has been penned to be able to complete the series, although the exact time frame for the final volume is still unknown.
The story is on CNN and additional information is available at the following fan sites:
