I got an email alert from Daily Variety about this, and I had to check the calendar to make sure it wasn't April 1st. Wow, it's really true. The Daily Variety article is pretty in-depth, but you have to be a subscriber to read it, so here are a few other articles:
here's a story via Reuters,
here's a short story about the deal being closed,
here's a story from msnbc about the sale and why Dreamworks didn't end up working out in the end,
here's a Bloomberg article.
*Very* interesting news.
