The Living Church now has a report on this with more detail, Windsor Report Response Presented to Bishops.
They have received a preliminary report from the Special Commission on the Episcopal Church and the Anglican Communion announced last September – for backstory see ENS Special Commission on Episcopal Church, Anglican Communion to meet and TLC Special General Convention Commission Appointed.
See the latest ENS report: Special Commission members brief bishops on progress.
The Commission will offer a full report, relating to the Windsor Report, Primates Meeting, and the Anglican Consultative Council, to the 75th General Convention approximately 60 days prior to Convention, i.e. about 10 April.
Then, as the General Convention of ECUSA approaches, a separate official commission will prepare formal resolutions for the Convention to consider. Membership of this commission was recently announced, see ENS Special committee on Church and Communion named. Although this is a separate body, there is a significant overlap of members between the two groups. The Convention meets from 13 to 21 June in Columbus, Ohio.
In a separate development, the Presiding Bishop has written to the other primates about the Listening Process:
see ENS Interview: Presiding Bishop supports listening process, writes to primates
Transcript: Presiding Bishop supports listening process, writes to primates.
This has been reported by the Living Church magazine as Presiding Bishop Writes to Primates.
The actual text of this letter has not (yet?) been published.
Meanwhile, in yet another development, the Diocese of California will hold its election of a new diocesan bishop on 6 May. This is thought to be relevant because the nominees include several persons who are in same-sex relationships. The General Convention will be asked to ratify the outcome of the election. You can read all about the election process of that diocese on a special website which contains profiles of all the candidates as well as of the diocese and much else besides.
