OK. I've got lots of reader feedback expressing confusion and dismay that they can't seem to find PowerPivot or the new PowerView in Office 2103. These two components are typically referred to as BI functionality. It seems as though the BI functionality will not be included in all versions of Office 2103.
The handsome Jeff Weir points us to this article from Chris Webb's BI Blog explaining the entire thing.
Here are some key points from Chris Webb:
"For regular, non-subscription, Office 2013 on the desktop you need Office Professional Plus to use the PowerPivot addin or to use Power View in Excel."
"Professional Plus is only available via Open, Select or EA licensing. This means that no regular retail editions of Excel include PowerPivot or Power View, you can only get them through a Volume License Agreement or Office 365."
"Office Professional Plus 2013 will be available via Office 365 on February 27th 2013. The cheapest subscription option that includes Excel on the desktop with PowerPivot and Power View is, as far as I can see, this one…"
"The Excel Data Model and IS available in ALL desktop editions of Excel."
I'll limit my comments on Microsoft's Office 2013 licensing decisions to two words: Soup Sandwich.
