I do believe what the guys@empeg say.

Remember: At the Mk1 they didn't have something like a production street booked and they didn't stock such amount of parts. The Mk1 was kind of "hand made". That's a reason why they didn't produce such an amount, I think.
And why should they tell us something false about the coming up of the Mk2. I think they know the'd loose many potential customers (or clients ) if they never start to ship a larger amount of units.
And if they sell enough units they'll earn some money with their great idea, too. So everybody will be happy, I'm sure.

You have 2 Mk1 units and are now going to get a Mk2? Some people have much luck
