Has anyone seen this article that seems to suggest the SMB2 file corruption is resolved?

The article is "last reviewed" June 2011, but files are dated June 2010 and I known Brandon Harker still had an open case with Microsoft last month. Someone (who is no longer active on Universal Thread) posted a link to this article on Experts-Exchange.COM as a resolution to SMB2 issues rather than turning SMB2 off and I just wondered if anyone knew anything about this fix?
