That's the plan, to move Latam Brasil(Tam) back to Sabre(they only moved to Amadeus a few years ago!).
But looking at the disaster that has been the IT department's integration of the websites, I wouldn't hold your breath for 2017. The websites still aren't finished, with many functions inoperable. Accessing the Latam website from Brazil you notice it still regularly drops back into the old Tam website(although with Latam branding).
