According to reliable sources, the NYSE filed an amended proposal with the SEC last Friday with respect to shareholder approval of equity compensation plans and discretionary voting of "broker non-votes." The SEC is expected to release the proposed rule today or tomorrow (with a 21 day comment period) - and then will be on the SEC's web site.
The other corporate governance listing standards proposals would then be handled separately - and may be a few months away from formal proposal by the SEC (as it seeks harmonization between the NYSE and Nasdaq).
