From the offcial PlayStation Forums:
"Patch 1.27 is well under way and will be released a little later this month. It is a pretty sizable patch with some exciting features. More on that later on when we get closer to releasing it. There is also a lot of server related maintenance coming with that and a lot of other things still in the works. (DLC 2 anyone?) But more on that later.
So, behave yourselves and a press-release with the changes in patch 1.27 will be released when a date and time for release has been agreed upon with all regions."
