Just saw this on Fr. Zuhlsdorf's blog:
Keep in mind that Pope Benedict had asked for feedback about the implementation of Summorum Pontificum after three years. Three years went by. There has been sufficient time for feedback. It’s time for the instruction.
It is my understanding that the Instruction is on its way, that it has been, if I am right, approved by His Holiness, and will be issued in the first days of March. That implies a signature date of 22 February, the Feast of the Chair of St. Peter. Documents are often signed on a significant date, but released later.
