Via arstechnica, The US Department of Justice (DOJ) is taking a closer look at Adobe's acquisition of Macromedia.

Spurred by concerns over the future of the high-end graphics and web authoring software market once the transaction goes through, antitrust regulators have requested additional information from the two companies. The DOJ is especially interested in what will happen once the old GoLive vs. Dreamweaver and Illustrator vs. Freehand competition ceases under the suddenly larger Adobe umbrella.

The article also states that it is not unusual for the DOJ to request more information for deals involving software, because it is harder for regulators to grasp.

Apologies if this is old news, I just got back from my vacation in antelope valley / mojave desert / southern california, and I'm still trying to catch up.
