Let me put it this way:
I could release a version of Act IV right now. I have several right here on my hard drive. However, everyone who's seen them seem to agree the edits we've seen aren't as good as they could be. The issue is coming up with an edit that meets the standards set by the previous acts and which is the best it can be.
I have to say that that is the MOST ENCOURAGING thing I have heard about this since the day I first heard of Exeter! Oh Happy Day! I hope and pray you also have copies of these blessed edits on other hard drives at other locations. Whenever you are ready to release your final edit, your public awaits!
