The Federal Trade Commission has stated that it will not oppose EA's pursuit of Take-Two Interactive. Following an investigation, the government agency concluded that no antitrust issue will occur, but left the door open to "take further action as the public interest may require."
This means all systems are go for EA and Take-Two to come to some sort of amicable agreement over how to bring the companies together. If that doesn't work, EA will probably just go back to throwing money on the table until Take-Two is ready admit she can't deny the sugar.
