If you follow anything outside the regular SQL Server world coming from Microsoft it should be Office and more importantly SharePoint. The two follow the same release cycle and as of today (July 16th actually) they have released a public beta for Office and more importantly SharePoint 2013!
If you are interested in the SharePoint 2013 preview you can head over here (http://technet.microsoft.com/en-US/evalcenter/hh973397.aspx?wt.mc_id=TEC_121_1_33) and grab a copy of it.

Over the next day or two I will be downloading and installing myself. If you happen to get your hands on it and find something cool please let me know! I’m going to try to pair it up with SQL Server 2012 in addition to 2008 R2 to take full advantage of all the new BI features like Power View.
