Many brilliant minds that are in the know predict not before 2060. I myself, using the clues given in the prophecies of old and even using the holy circle equation have pinpointed the end beginning in 2085 and ending in 2092.

No man knows the day or the hour, but I think a few do know the year. I think plenty of life left to live, but there will be a progressive buildup of catastrophes until it all hits the fan in 2085.
