"I hope to someday return to finish up the story lines in Volume 4, but when that will be, I have no idea. I can only hope that when I get around to it, Jim Lawson will still be willing to draw it!"

From a response on July 9th.
It seems like a minor thing, but saying "I hope to someday return to finish up" volume 4 is different than him saying, "Maybe I'll do it, but I doubt I will," as he's been saying for a few years. Maybe a small distinction, but it seems important.
