No details have surfaced so far on the Internet about the lineup of computers that should have replaced or existed alongside the PU1 units. A photo from Tokyo's 1982 Microcomputer show (held in late May 1982) indicates the PU10 would have had a smaller case than the original models, with a recess to attach the keyboard (resembling the later YIS805) and still two 5 1/4 inches floppy disk drives.
A PU10-S likely launched alongside the PU10-D. Upgrades were planned for March 1983 (PU10-DE, PU10-DF, PU10-DK and PU10-SF) but were probably never released.
