There will not be a patch coinciding with the ladder reset happening on September 28, 2010.

The aim of this reset, and all resets, is to refresh the game. Giving that enjoyment of competition in racing to 99, finding an item no one else has yet, or even being the first to slay Andariel. A fresh ladder as you know is really about the rarity of items, a fresh economy, and the fight through the game starting from scratch. Ladder is about challenging yourself. There are obviously going to be people who came in half way or just don’t level as quickly as others, and while we definitely like for everyone to have a good time and feel like they got done what they wanted to, we have to cut it off at some point. Right now six months feels like it’s the right amount of time to keep those racing to 99 appeased, and the economy fresh.
