Tech Ed 2009 was kind of disappointing from the SharePoint 2010 front. Ahead of time Tom Rizzo told us his SharePoint Overview and Roadmap would only include sparse 2010 details.

If you haven’t yet, read How to get a copy of Office 2010 technical preview. I signed up on the wait list which doesn’t include SharePoint pieces. Email expected in July or August for an invitation to the client downloads. The SharePoint Technical Preview is invite only and limited.
Beyond that, there are some videos of Office and SharePoint at Microsoft® Tech·Ed Online. We already knew about the 64 bit stuff from the Microsoft SharePoint Team Blog Announcing SharePoint Server 2010 Preliminary System Requirements.
