We've had discussions in the past on whether or not Harbour Lights could release 'new' versions of previously issued-and-retired limited editions or not.

Other examples:
Southeast Block on the Move
Cape Hatteras on the Move

I couldn't find the original thread I started with the approximate title of "Could Harbour Lights reissue retired limitied editions...", but here are the threads that came up.
