Do they still sell xbox 360s in stores like toys R us with the old zephyr chip?

I just want to be sure that if i buy an xbox 360 now, it will NOT have the old 90nm zephyr chip. And it WILL have the new Falcon 65nm chip. I really wont be able to send my xbox 360 to microsoft if i get RRoD because i live in the Middle east. And i dont think there is a factory here, since the xbox 360 i will be buying is imported from the USA
