The Fw-200 volume is not a revision, but a complete new work by Chris Goss.

I understand your confusion about numbering, but the Fw-190 series seems complete in its coverage where the Ju-88 series is missing substantive coverage of the operational careers of fighter and recon variants. Perhaps one of the other posters knows more, but if not, time will tell. I would not hold my breath for Fw-190 v4 though.
