Activision boss Bobby Kotick has expressed concerns about the possibility of a merge between EA and Take-Two.
"That's concerning, sure," he told Reuters. "When you think about one company in control of the sports category, with no competition from anybody else, that could be a challenge."
That the deal would also knock the Activision-Vivendi deal out of the Guinness Book of Records is also playing on his mind, we'd wager.
The $18 billion deal currently stands as biggest in the history of video games, but it's expected that an EA / Take-Two merge would be worth significantly more. Now that GTA IV is out, talks between the two companies are expected to start soon.
