Performance Point 2010 is completely redesigned in order to play nice with SharePoint. This actually introduces a very interesting workflow for authoring PPS dashboards. All PPS objects are stored in a SharePoint List and are manageable in there. For example you can create new a Data Source connection as a new SharePoint list item. Some other common tasks are now doable without Performance Point designer.
Microsoft SharePoint 2010 supports alternative browsers such as Firefox and Safari. This is a bold move and I hope that Reporting, Excel, Visio, and Performance Point Services on SharePoint do that as well. I imagine the joy of all Mac users when MOSS 2010 becomes available to them.
Silverlight Bing Maps control has been announced. It is in CTP stage right now and only available to Microsoft TAP program subscribers. From what I saw during the presentation, this is the next step forward in maps/geo extensibility.
