Not long into the SharePoint Conference 2011, it was announced that the next SharePoint Conference will be held in Las Vegas, November 12-15, 2012. This is the first time that a the next SharePoint conference has been announced at the preceding one. In fact, the last conference was in 2009, two years ago.
Back to Vegas (where it should be!) and only a year from now. Does that mean that 2012 will bring big things to the world of SharePoint? I think that you can bet on it.
Given that the last two conferences have used the same url, I would recommend keeping an eye on http://www.mssharepointconference.com for any updates.
