Yes - they likely will :-(
They produced 7020 for the backers and I think there are also some
or all for preorders, but I didn't hear anything about 7010 in production
yet.

Wonder why they added a flash chip, when they could have gone without.
Is this a pin strapping configuration, or something, which can be
