According to Canwell, IDW is planning to release a second volume of Bringing Up Father and continue Rip Kirby post-Raymond.

Canwell: I expect we’ll do about twenty volumes – Steve Canyon essentially ran forty years and as with our Terry volumes, we’re collecting two years in each book. Given that our Dick Tracy series is up to Volume 12 and the phenomenal response to Rip Kirby convinced us to continue that series into its John Prentice years, I like to think readers will support Canyon and allow us to reprint the entire series.
