My guess is either MathUser is trying to spark something. Or they are young and were taught about the Wars from someone who grew up during the last three movies. 'Sequel Trilogy' in the context of Star Wars shows a lack of understanding the history. But if you hadn't thought about it, and all you remember hearing was Prequel Trilogy, then you might assume Sequel Trilogy. Need to see a few more posts to make a judgement.

MathUser if you want people to consider your idea, change the thread title to 'Petition for digital replacement of Yoda in Original Trilogy' that should gather some choice words from various members around here.

I don't think 'sequel trilogy' is used in this way over at TF.n. Did a search through their forums and getting almost 5k hits, but the top 10 are all talking about Episode 7-9.
