The Microsoft SharePoint team has announced on their official blog the following amazing statement (emphasis added):

“To ensure the best possible experience across multiple browsers we’re focusing our SharePoint 2010 engineering efforts on targeting standards based browsers (XHTML 1.0 compliant) including Internet Explorer 7, Internet Explorer 8 and Firefox 3.x. running on Windows Operating Systems.  In addition we’re planning on an increased level of compatibility with Firefox 3.x and Safari 3.x on non-Windows Operating Systems.  Due to this focus Internet Explorer 6 will not be a supported browser for SharePoint Server 2010.”

Amazing! Even IE6 is seen as a dead technology by Microsoft’s standards. Hopefully with news like this and Windows 7 pre-release excitement the browser might finally be relegated to the hall of technological mistakes. They also announced the WCM features in the next version will allow much greater control over the markup which may finally make SharePoint a real candidate for WCM for public-facing sites!

The announcement does also focus that the technological requirements will be all 64 bit and based on Windows 2008 as the host platform.
