The latest rumor involves the location that will build the iPad mini. While most would probably assume it would be built in China, in a Foxconn plant, it might be that you have the company right, but the geographic region wrong.
Tech blog Macotakara claims that a reliable source in China (not Brazil) has told it that the iPad mini will be produced in Brazil, with Foxconn ramping up production beginning in September. It makes sense; there is not an unlimited supply of bandwidth at Foxconn's Chinese plants.
Most believe the device will have a non-retina display with 3G capability in some versions. One source that claims to have seen a prototype said that the device will be thinner than its rivals.
