Brazil has been rumoured to wanting M1 Abrams for some time so maybe...
There's some irony there Greg, for as I've read It's very odd that Saudi Arabia gave the go-ahead for the development and R&D phase of the EE-T1 at a cost US$100 million.
In August 1989, the Saudi Government announced an order for 318 Osorios (renamed Al Fahd, Lion Of The Desert) worth US$7.2 billion, the contract was never signed by Saudi Arabia.
The fact that the Engesa Osório EE-T1 out performed the original 105mm M1 Abrams [I appreciate the modern 120mm M1A1 is far superior in capability to the original 105mm M1!], when Saudi Arabia conducted a competitive trail of M1 Abrams, Challenger 1, AMX-40 and the Osorio. Even though the Osorio emerged as a winner in September 1989, the decision was taken by the Saudis to instead in secrecy purchase the M1 Abrams, to replace their AMX-30's.
