I'd just email them and ask if they could provide you an email list.. they may be hesistant to give it out, which is understandable but you could then request they send an email out to their customer base or mention it in the
next communication they send out. As I understand.. they are arcade collectors as well.
They are still in the process of making the zvg batch.. I imagine they will
be emailing everyone at least tracking information when it is done.
Creating a standard Multivector cpo and metal CP makes it easier for people to contemplate creating a multivector.. and should enhance their sales for a future run of the product. So it would be a WIN WIN.
Oh I would also make a post on the news group Rec.Games.Video.Arcade. Collecting
