I know this is a month old, but I'm just getting caught up on some reading/viewing... If you also haven't seen the day 1 keynote of MIX 09 and care about where your craft is going, you need to watch at least the first 8 minutes of the video and then if you're short on time jump to the 97 minute mark and watch the demo of Expression Blend 3.
