I'm hoping they do MBr or CCCr next. Those are the only ones I want to go along with my MMR.
Realistically from a demand perspective the 7 candidates for remakes (assuming the emulation software is not enhanced for WPC-89) are:
MMR
AFM
MB
CC
CV
TOTAN
SS
The other WPC 95 games (NBAFB, NGG, CG, CP, JY) are all less than 5k, with most going in the 2-3.5 K range. And then safecracker, which I cannot imagine selling in any great numbers.
