Bioware has put up some exclusive screenshots and a short trailer showing off some of the Mage class abilities in Dragon Age: Origins. It requires you to log in as a member of their forums however, so I didn't investigate much further (not to mention Bioware's Dragon Age website usually crashes my browser), but I'm sure some people will be interested enough to check them out in the Dragon Age gallery and may want the heads up. Assuming you don't frequent the places I rip news from, of course.
