"Lord of the Rings" sequel!

[Sardy]

(Forgive me if the has been discussed before, but I looked and could find nothing...)

This is a thread for discussion of sequel(s) to The Lord of the Rings. What epic history do you think Tolkien might've envisioned for the Fourth (and Fifth, etc.) Age(s)? What writer might be capable of carrying on Tolkien's tradition and adding to Middle-earth? (Tolkien himself has stated that he always envisioned Middle-earth as an organic writing that could and should be added to...).

And also, what plans (had he lived long and not abandondoned it) might Tolkien have had for The New Shadow, his unfinished (barely started) sequel? True, he had his doubts about the project from the outset (but what writer doesn't?). Surely, the genius imagination that could grow The Lord of the Rings from the humble tale of The Hobbit, given time, would have made a remarkable piece from The New Shadow...!
