2 major recent changes with MSDN AA
First up, there is now a second MSDN AA subscription called Designer AA to compliment the 'traditional' subscription (now called Developer AA). It's a trimmed down version of the original MSDN AA subscription, tailored specifically to web designers. Designer AA subscriptions are available to any approved institute teaching Visualiation, Illustration, Design or Art degrees.
Secondly, Developer AA also has the full Expression Studio included. So finally there are some WPF tools included in MSDNAA subscriptions for university students to use.
