More Salinger Books Coming?

I read where there is a new J.D. Salinger biography coming soon and that the authors claim that there is additional Salinger fiction that will be published---novels, short stories, whatever.  Okay.  That's good, but I am hardly overly excited.  Salinger is a good writer, rightly lauded, but I also add that he is overrated.  The fact that he didn't publish anything for the last 50 of his life and didn't appear in public made him a true recluse.  If he had published what's in the vault while he was living he probably wouldn't be as popular as he remains today.
