From October 2009 to October 2012, Saturn transits Libra. During that time period, all members of the Pluto in Libra generation will experience the Saturn conjunct Pluto transit.
I won't go into all this transit indicates, as it's complex, but in basic terms, the people who have natal Pluto in Libra (roughly from 1971 into 1984) come into their authority within the structures as they exist through this transit, and this relates in particular to social authority.
A big part of the Pluto in Libras' generational authority is leadership into new social/relational standards. These involve the development of a more honest, just, and power-balanced framework from which to relate, along with more mutually supportive, freely-loving and workable relationship constructs.
Libra is a cardinal sign. It starts things in a new direction.
As the Pluto in Cancer generation passes off the Earth, the Pluto in Libras will be the only cardinal Pluto generation in the works until the Pluto in Capricorns being born now become adults. The youngest members of the Pluto in Libra generation are soon to be heading into their Saturn returns, and this generation as a whole comes of age under the Saturn in Libra transit.
The "deferring to others" quality of Libra gets a big check here by Saturn as the Pluto in Libras are challenged to own their authority on this front.
As the Uranus in Aries - Pluto in Capricorn squares and cardinal Grand Crosses continue to form in the cosmos over the next years, this generation is going to have to step up.
That said, since Saturn began its transit of Gemini in August 2000, all Pluto generations currently alive on Earth have been, in succession, experiencing transiting Saturn conjunct natal Pluto. The upcoming transits of Saturn through Scorpio, Sagittarius, and Capricorn until December 2020 pretty much bring everyone on the planet into the mix.

From March 26, 2010: Pluto in Capricorn: All Hands on Deck.
The new millennium brought us into some serious, tipping point times on Planet Earth, and Saturn is attempting to make us aware of our responsibilities, generation by generation.
Saturn is ensuring that anyone with the ability to do so stays right at the white-hot, Plutonic cutting edge, keenly aware of what we're meant to morph and change generationally through personal efforts.
The mutable Pluto in Virgos (born roughly 1957 into 1972) came into their own authority in this way as Saturn transited their natal Plutos September 2007 into October 2009. This recent transit of Saturn through Virgo coincided with a Saturn in Virgo - Uranus in Pisces opposition series that was last experienced in the mid-1960s when Saturn and Uranus were in opposite signs (Saturn in Pisces, Uranus in Virgo).
Many Pluto in Virgos were young children or were being born at that time, and the energy and impetus of the radical 60s permeates a lot of the generation. Working with the oppositional tension between security and structure (Saturn) and revolutionary freedom (Uranus) as well as coming up with just the right mix along the polarity is part of the challenge and authority of the Pluto in Virgo generation.
