If you are attending TechEd Europe in Barcelona 7th-10th November 2006 then then check out the following session about XNA GSE.

I can't link directly to the session (great website guys!). To find it you need to use the session search page and search for XNA. The speaker, Rob Miles, is a lecturer from University of Hull who has been on Coding4Fun and spoke at GDC and has somehow never managed to bump into The ZMan (next year I'll buy you a beer!)

Here's the abstract:

DEV302 Microsoft XNA and the Future of Game Development
Rob Miles
Fri Nov 10 10:45 - 12:00
XNA represents a major milestone in the field of game development, bringing game creators a unified platform and the safety of managed code. It also greatly reduces the difficulties faced when starting out in game development, closing the gap between idea and working implementation. The recent release of XNA Express gives programmers a chance to get to grips with the XNA framework and use it to create content for both the PC and the XBOX 360.Beginning with an overview of the XNA platform and the XNA Express development tools, this demo packed presentation then moves into the ‘nitty gritty’ of game development using XNA, leading to a fully realised casual game running on an XBOX 360. Whether you are a seasoned games coder, or a programmer thinking of moving into game development this session will give you plenty of food for thought and information to get you started.
