Microsoft Tech Ed 2008 is coming up in early June. This year they are splitting it into two parts: IT Pro and Developer, each of which gets a week. I think this is a good move, as it allows the Developer week to be focused on topics developers care about. They've done this for a couple years now in Europe and it has been successful there.
The developer week is June 3-6.
I'm a co-chair for the Developer Tools track, which covers Visual Studio, all the languages and related topics. I think we put together a great set of speakers and topics in this track, so I'm very excited about it!
I'm also one of the featured speakers, and you can see details about all the featured speakers in a nice little Silverlight app.
