http://www.wizards.com/default.asp?x=magic/preview/shmpackIt has a sample pack of shadowmoor opened. They've blanked everything but the name, Art, and mana cost but it's still real cool.
If it's truly a random pack this expansion is going to be full of hybrid mana. I'm personally digging the 2/B Hybrid. It's mechanics will probably be lame but the thought of spending 2 colorless to make B work is pretty cool. Tron???
