here are some values:

GW7: 32 Mb
GW8: 256 MB = 32 Mb
SonicCell: 128 Mb
E60: 512 MB = 64 Mb
E80: 1024 MB = 128 Mb
and if I remember correctly, Pa50: 32 Mb.

I dont know about G70, but could be 192 Mb indeed.

Anyway, these values are important, but they dont say much about the quality of samples though.
They are 16 bit lienar equivalent, so the compression or the samples in the instrument's actual memory is a very/more important issue.
