The proposed 7100A or E modems for the dev-kit are ok for USA and EU, but not for the rest of the world.
I have ordered the dev-kit and I live in Australia. These are our LTE frequencies:

It looks like these modems would be suitable for Australia, New Zealand and South America, though only the 7500 states 3G support:

I do very much hope that these bands will be offered in the final phone. There must be lots of backers, or potential backers, from these countries. I am with Telstra, and for me, the LTE B3 (1800MHz) and B28 (700MHz) bands are the most important.
