I wouldn't hold my breath over it. Naughty Dog said that the news (patch notes?) would be coming out at the end of the month, but they've been saying that for quite some time. I wouldn't be surprised if it were magically delayed again only for the hype machine to start back up.
"Patch 1.17 and something new for Uncharted 3 Multiplayer will be deployed next week. Full details will appear on the PlayStation and Naughty Dog blogs. Get those reading glasses cleaned as it’s going to be a long read."
