Will a "definitive" version of The Silmarillion ever be released?

[Inziladun]

I'm not nearly well-versed enough in the laborious process Tolkien had in writing the stories of the First Age to debate with some of the scholars here.

However, Tolkien himself is gone and unable to tell what his ultimate plans for consolidating the stories into a comprehensive volume were. That being the case, it is very unlikely that any version or variation of The Silmarillion will ever appear that will be universally accepted by both critics and readers. I think CT has done as good a job as can be done with the material he had to work with, and as I've said before, I really don't know anyone else in a better position than he to try and assemble the stories into a cohesive work.
