I may be going mad, but I've volunteered to do 5-minute presentation in front of several hundred people at the Microsoft Visual Studio 2008 launch event at Birmingham ICC on 19th March, in a "speaker idol"-type contest featuring amateur speakers from the developer community.
I have been using the Express editions of Visual Studio 2008 for a few months, but have not explored many of the new features. I have a couple of ideas in mind, one based on the Observer pattern nugget I did at NxtGenUG last month and another based on the Visual Basic Power Packs, which is top secret at the moment.
