Me? I'm thrilled with this news. Yes, it's going to take longer to complete the story, but you know what? These books are going to be around for a very long time. Do it right. Do it the way Jordan would have wanted it. Tell the story the way it should be told. Don't rush it, and don't give these long-traveled characters short shrift at the end.
This is the right thing to do, and I'm happy to see it, even if it does mean waiting longer for the resolution. The story deserves it.
