We've recently completed a revised version of the Diablo II 1.13 patch that removes the increased stash size. A larger stash will unfortunately no longer be a feature included in patch 1.13 due to the previously mentioned concerns. As higher priority work continues on Warcraft III we're hoping to complete our quality assurance tests for the 1.13 patch in the next few weeks. But as always, the types of issues that may appear and take higher priority are rarely foreseeable. We continue to plan a release based on our best intentions.
