I have ordered the 149-1 and will order the 149-2 as soon as they are taking orders at Sonic Highway.
Is there any idea as to how many modules there will be, assuming sales are good.
I understand the second to be in many ways an add on to the first that will create a feature not available in the SOU.
What would the additional modules be if they are produced?

Thanks,
TD
