I found the post from Bashiok. The patch wasn't announced explicitly by him, but he gave us to understand that something will be changed in this Reset.
This Reset was supposed to be in September 28th, but Blizzard changed the date to October 25th because they wanted to "figure out some things" before reseting the Ladder.
Here's the post from Bashiok:

We're holding off on a reset to figure out some things. We'll let you know as soon as we do.
