Yesterday I blogged about the new BI features that will be in Excel 2013- one of them being Power View. He’s some more detail, particularly about what’s coming in Power View in the next version. link
It looks like you’ll be able to use this new version in Office 2013 or SharePoint 2013- which begs the question- will you need to pay for SQL Server 2012 any more, to use it in SharePoint? I’m sure the answer will become clear. But in the meantime, you can look forward to hierarchies, maps, drilling, and pie charts.
