The way it is going at the moment, it will reach $500 before the end of the year.
For me that is very possible to happen because the performance of ethereum right now is very nice and very well, i know that they can even do more, because ethereum is the best altcoins and i think the price of ethereum is will rise even $600 in new year, because as of now the price of ethereum is $484, and i think etehreum will rise very fast before this year will end.
