Since the release of Visual Studio 2012, business intelligence developers have been limited in how much they could use this tool due to the fact that it did not support BI project types (SSIS, SSAS, and SSRS).  Today, that limitation is now gone with the release by Microsoft of SQL Server Data Tools – Business Intelligence for Visual Studio 2012.  With this release, BI professionals may now fully move onto Visual Studio 2012 for SQL Server 2012 project initiatives.

You can read more about this release on the SSRS team blog and SSAS team blog, or download the code from the Microsoft website.
