Rob McGinnis posted at the NWN2 boards today that the 1.13 patch will be avaliable tomorrow (PST).

"There has been a lot of discussion about patch 1.13’s release.

Everyone wants to know when the patch will be released. The short answer to this is tomorrow!

We have made the patches available to the hosting partners, now we just wait for them to download the patches and make them available for the autoupdater.

We will activate the patches tomorrow (PST) after everything checks out."
