New Gormenghast novel?

I just saw this news about Mervyn Peake's highly idiosyncratic masterpiece. I have the omnibus edition of the Titus books, so I've read the little scraps of the story included there. I'm glad it's not some later writer who was asked to complete the manuscript or anything along those lines--hopefully his widow would have had a good feel for what he wanted to accomplish with the story. I'm somewhat concerned with whether the book will live up to the earlier ones, but I'm pretty sure I'll read this once I get a chance, despite those concerns. I've reread the first book fairly recently, but I ought to reread the second and third soon too.
