Greatly exaggerated. In fact, I've been working on a straight up TPM edit as I've been doing Duel of the Fates. A lot of the ideas and concepts I'm working on are actually going to work well with standard prequel fanedits.
Duel of the Fates is a huge project for me, one that will take a while to complete. What may end up happening is I continue to work on that in the background while releasing TPM and re-releasing my other Star Wars edits, with fixes, addition of new deleted scenes, and HD picture quality. This includes the revised version of ROTJ. I got some pretty cool ideas at play here, and I may be able to make my perfect version of the prequels now. The one that won't change much is probably ROTS, I'm pretty happy with that as is with some little changes.
