Holk,
At this point number 3 on your list is the main culprit. If they can market this properly then we will see the big push in SP. Coupled with the product rollout of course.
I think a partnership with a NA or European entity would be a major plus but not a deal breaker at the moment. I think the majority of chips come from China/Asia. I sure would like to see it though.
I am really looking forward to a follow up on production with solid $$$ attached. If all goes according to plan that should be any time now.
