Thanks ae86_16v for reading the article and liking it enough to request more.
I actually started out writing the final article with some concepts in mind and while doing additional research, discovered that I was wrong about some of those ideas. That combined with what appeared to be relatively little interest in the subject by others caused me to abandon the final article. Besides I struggled to find the time to write the article.
At this point I would say I don't think that there will be a final article. But you never know.
In regards to your question about model designation, st-anger addressed that question here
