I asked Dean about Aroo 2 and Ben Casey and below is his response:

Re: AROO 2, I'm still trying to locate the 1954 dailies. Jack Kent Jr. has sent the art for the rest of the book, but he's missing these. The book is officially off the schedule until I locate the strips. When I find them, we'll relist.

CASEY is still in the gathering stages. We just found of reference photos Neal Adams shot. Getting closer on the art…but not there yet.
