It depends on who you ask. Your question is Astrological, not Astronomical.
That said, some of my closest friends are astrologers, and actually, we will be entering the age of Leo in the next few hundred years. Then Capricorn, then Cancer. (Not everyone agrees that we are currently in Aquarius! Not for a few hundred years yet!)
The age of Capricorn looks just like now. We're far from entering Sagittarius, even. That was just "Hair" or hippies getting excited about the changes then, that have been since rolled back.
The best astrologers are psychologically minded. Consider the sun-signs yourself. If you want to consider the moon-signs and the rising-signs, go ahead. How about the asteroids, and Pluto. Then apply them to ages.
A wise man knows that flipping coins or picking yarrow stalks, as Taoist I-Ching divinators do, this is as effective as depending on the stars and planets. Probably the best predictor of any life is a farmer's almanac for your region. Divination is good. It is a waste of time to predict the next astrological age.
