I have been following a Connect item about Visual Studio 2010 and the lack of support for BI project types.  This recent comment from Jeff Bernhardt, Product Unit Manager for SSIS caught my eye today (emphasis mine):

First of all, thank you to those customers who have offered feedback regarding how your work and productivity are impacted by Integration Services (SSIS) not yet being available in Visual Studio 2010. As developers ourselves, we certainly understand the frustration you have reported in having two Visual Studio instances installed and maintained on your development machines. While this side-by-side configuration works, it is certainly a less ideal solution to operating SSIS from within VS 2010. Unfortunately, the staggered ship cycles of the two products (VS and SSIS) and some convoluted dependencies did not allow us to reunite the development environments of both tools until the next version of SQL Server.
Meanwhile, please be assured that SSIS projects continue to be supported by Visual Studio both now and into the foreseeable future. Until the next version of SQL Server, we will be happy to discuss with any Visual Studio 2010 customer ways in which they can optimize the interoperability of VS and SSIS. We apologize for any inconvenience and are committed to improving your user experience both now and in the future.

All I can say is holy smokes.  The "current" version of SQL Server RTMed a week or so ago.  The delivery date of a "next" version is at least a year away, in a best case scenario.  Leaving developers out in the cold for this length of time will seriously impact the business discussions around BI projects.  I am at a loss over this decision.

When you add in the fact that little if anything was added to the SSIS product in SQL Server 2008 R2 it makes you question the dedication it enjoys within the product team.

I know from personal experience that Connect items are heavily monitored so if this also strikes you as something that needs to change make sure you vote (and get others to do so as well).  It sounds like a grassroots effort will need to take place for the decision to change.
