He said something was coming which would interest me, but not that. As you say this does not rule out that.
He said they basically put the SP-10R power supply into the GR2. I asked if that would happen with the G and I think he sort of implied that it wasn't necessary on the G and wouldn't happen. I could not work out if he meant that the G power supply was already that, or that the differences would not make such an improvement worthwhile. Mysterious, but if I take him at his word there is no G2 in the pipeline.
I'm interested in a GR2 because my G, at about 20kg, has turned out to be too heavy for my old back to heave around to audio shows. I can't believe I've reached an age when convenience is decisive. My younger self is turning in its booth. This and the platter spin-up raise doubts about a G2 being launched as a 'breakdance' DJ tool. I'm not sure DJs want a 3.6kg platter which, according to Technics has "more than twice the rotational inertia of the Mk5".
The G motor with a light platter - now that might interest DJs who value very fast spin-up, but that wouldn't really be a G substitute, it would be a Mk7 upgrade.
Either way, I think a GR2 has my name on it.
