I don't know why this time Microsoft has generated this confusion to the users...
As you know, Microsoft has release in these days Microsoft Visual Studio 2005 SP1, and I've received questions from friends about whick version to install if you have VS2005 Standard or Professional Edition (the most widespread).
If you reach the separate SP1 download pages (maybe via a Google search), you're in confusion: whick is the right version?
Visual Studio® 2005 Team Suite SP1
Visual Studio® 2005 Team Foundation Server SP1
Visual Studio® 2005 Express Editions SP1
The answer is on the VS2005 SP1 main page: Visual Studio 2005 Team Suite SP1 is the package that includes SP1 updates for Standard, Professional, and Team Editions of Visual Studio 2005.
Is it clear now? 
Microsoft, please show this information also on the download page...
