Microsoft is holding a mini-Mix in London, September 11-12. It appears to be focused on Silverlight, Expression and Windows Live, and speakers include Scott Guthrie of ASP.NET fame (but now with wider responsibilities) and Danny Thorpe of Delphi fame (but now at Microsoft and working on Windows Live APIs).

Windows Vista and Office 2007 may have under-delivered, but this stuff is pretty interesting; worth a look if you can make it. Of course I’m particularly interested in the Day 2 session called “Sneek peeks”.

It’s a while after Mix in Vegas earlier this year, but Microsoft’s Daniel Moth says there will be new content.
