Hi everyone,
This is what Iīve read on a Brazilian blog.
The blogger met Suzane Rubin on the T-Mobile Arena, and posted that she told him that they would not change before September, and probably only in October, with a 1-month notice.
I have a booked roundtrip Sao Paulo to Dallas in August, so I hope he is right and this information helps !

I donīt know him, but I follow his blog.
You can check it (in Portuguese):
