Microsoft has made a beta version of Microsoft Expression Web available. It's a big download: the web page says it's over 195MB! I'm kinda curious about this but there's not enough information on the web page to warrant downloading and installing it so if anyone's got any information, drop me an email (tony !at! tonys-links).
Microsoft has made XML Notepad 2006 available. It's billed as a browser and editor for XML documents.
