I actually doubt this merger will go through. This would put AT&T far ahead of Verizon in term of subscribers, even if they are less desirable due to the low ARPU. There isn't enough churn in the wireless market to balance the AT&T and Verizon out over a reasonable time, and Sprint would now be a distant third. Effectively this will shut anyone else out of the National carrier business, and eliminate the possibility of any new MVNOs, since customer acquisition costs would be very high, and you only have two parties to negotiate licenses with.
