i thought that the examiner said that he was chuunin level already, after he said the exam ends here

on A/A's translation its "sasuke, sorry, but the chuunin exam ends here. you are chuunin level already. if you are a ninja of konoha, be useful to konoha."

its really something for the high council, kages, and diamyos to decide
i think so too, to bad both kages died and the rest fell asleep and probably evacuated after they woke up
