Hi Fran,
I'll be visiting the Frankfurt Fair on Sunday and hopefully I can get a glimpse at the new VA 7. As far as I am informed it is supposed to be the replacement of the G series. So far I only got the informations you have already posted. There is a magazine called Tastenwelt "key-world" where Roland had an ad of the new gear.
I'll inform you about my opinion on Monday or Tuesday in this forum.
Markus
