Seriously though, "youch!". This is gonna be, no, it is a pretty heavy blow to adobe I assume. For a company that supposedly treats its employees like crap from time to time (just taking that from a comment off reddit, not sure if it is true), I can easily imagine more than one scenario in which the breach was made. Sometimes you shouldn't worry about attacks from the outside as much as the inside.
So source code has been breached, information regarding customers has been thrown out adobe's wazoo, and I'm certain you're gonna be getting all of about 1,000 updates from adobe next week.
