maybe they meant PGM3, that's just some kind of Linux based SoC that could have done the CV1K stuff I believe.
PGM2 really isn't much of an upgrade from PGM1, which in turn isn't really much of an upgrade from the NeoGeo (in some areas, it's actually less capable) Aside from a better CPU, *maybe* better sprite fill-rate, a 'simpler' sound system, and a single extra bit of colour depth on the sprite/background layer PGM2 is really just the PGM1 hardware rearranged a bit.
