I think it should happen but..

Personally don't see it shaking up the wireless industry that much except for the better. I'd imagine that wireless providers wouldn't be offering side perks if it were for T-Mobile Tuesday and the other things they give away such as Netflix.

VZW and ATT both have pretty solid footing in the wireless arena and other telecoms are already kind of entering the market as well (spectrum, comcast). I don't see the merger effecting it that much.

FCC Chairman is ok with it..

"FCC chairman Ajit Pai’s support for the latest iteration of the merger came after the companies agreed to several commitments, including deploying a 5G network covering 97% of the population, reaching deep into rural areas, within three years. Sprint also agreed to divest Boost Mobile, a wholly owned subsidiary focused on prepaid wireless plans. T-Mobile already owns Metro by T-Mobile, the prepaid carrier until recently known as MetroPCS.
