It is not expected to find Alexander by anyone. It is expected to find an important general or someone close to Alexander though.
The tomb date is greatly varied now, between 100-400BC but before Christmas where excavation will be done to the lower outer part of the tomb it will be possible for a ceramic analysis to be done that will pinpoint the date within 2 years.
A quote: "Archaeologists and the Greek ministry of culture warn against such speculation, especially since Alexander the Great is known [sic] to have been buried in Egypt."
An unfortunate turn of phrase. I would have said "is thought to have been buried in Egypt" or "is said to ...", since no one has definitively located Alexander's tomb.
Yes we haven't located it in modern times, but that is irrelevant. We have tons and tons of sources that mention Alexander's tomb in Egypt. There is little doubt that Ptolemy I controlled his body and buried it in Egypt. Julius Caesar, Augustus, Caligula, and many other Romans visited his tomb. Some of them even looted it.
I love the story of what Peter Green calls "Alexander's Funeral Games" - the battles of Alexander's generals to secure his body after he died and use it to legitimate their own claims to rule. Such a great illustration of the role of symbolic gestures in history.
Alas no. He had an official heir, Alexander IV born after his death aged 32, and possibly another son to a mistress. Both were assassinated in their teens.
