Noticed via MikeG that Microsoft Expression Graphic Designer (CTP) and Microsoft Expression Interactive Designer  (CTP) were out today. I was a smidge confused about which was which and for what, so I asked a smartie involved with the project what was the difference. Here's (paraphrased) what he said if you're confused as well.

You'll likely remember that Microsoft bought Creature House Expression 3 back in 2003 and that was code-named Acrylic and that is the father of the Expression Graphic Designer. Vector-based art is tantamount to voodoo if you ask me. I can barely make icons.

There's some nice videos and demos to check out.
