Yep. In the past five years they've had four different suitors. In 2011 it was AT&T (blocked by FCC/FTC), in 2013 is was Softbank/Sprint (could not get enough assurance from FCC/FTC the deal would not also be blocked) and Iliad (French telecom, couldn't raise enough cash to meet DT's asking price), and in 2015 it was Dish (similar situation to Softbank/Sprint). My guess for the next suitor will be a cable company like Comcast or Time Warner Cable shortly after the 600 MHz auction.
