In his blog, What Does the Prayer Really Say, Fr Zuhlsdorf has a post about a seminarian who claims that a poll has indicated that a majority of seminarians would prefer to be ordained in the older form of the rite. Furthermore they indicate a preference for Mass celebrated in the extraordinary form.
Unfortunately, no further details are given of the poll, so one must assume that it was conducted informally, and relates to one seminary, which is probably in the USA. It would be unwise to extrapolate the findings, and apply them to all seminaries in America, or the world. However, it would be very reasonable to identify a trend. Such a result would have been unthinkable ten years ago.
It is often said that what happens in America today, happens in Europe tomorrow. I would be surprised if the results of this poll were not replicated all over America in about three years and this side of the Atlantic in ten.
