Unfortunately, we don't have any additional Wellman in the works at the moment, but there is a terrific two-volume set of JOHN THE BALLADEER forthcoming from Haffner Press that is sure to be the definitive edition for the John stories once and for all. We have no association with Hafner Press, but we sure love their books. You can pre-order it here.
Thanks for your interest in Manly Wade Wellman, and our books!
