Unfortunately, we will not be able to help or give advice on product availability questions. These topics vary greatly between different markets/regions. So I'd strongly advise that you get in contact with your Local support and discuss the issue with them, as they are well-informed about your region's available products more than us on this global, user-based forum.
EDIT: looking at your local Sonymobile.com page, I can't see the XZ2 Premium on the list of phones even with a "coming soon" tag. That might indicate that it will not be released in Brasil.
