The Government will have to prove its case but I think AT&T should know the likely outcome as this is far from the first time that antitrust laws have affected their business plans. I was suprised to see the second largest wireless company believe it could acquire the fourth largest and have it pass review. The result would have been 90% of the market shared among three companies. I haven't read anything about the Google acquisition of Motorola Mobility to have a feel for whether or not that one can fly.
