And even download it and install with Odin manually later. Or you can find them at XDA Forum and SamMobile website too. With Samsung Galaxy S3 unlocked bootloader, you can try other region firmware too. For example, my Samsung Galaxy S3 is Malaysia unit and loaded with South East Asia firmware. I can install UK I9300 firmware on my Malaysia SGS3 since international SGS3 hardware is the same. So no need to wait on your region firmware for long time and try other region latest firmware first. Europe region always get the latest firmware first. And Malaysia will get it several months later…
