Is 5G the real reason Verizon is moving to IP TV?

Just saw this article: http://ift.tt/27RMmC4

It claims:

Verizon CEO says there's no reason why FiOS, now only available in the Northeast, couldn't go nationwide with a fixed wireless service.

So is this the real reason Verizon is sold off big hunks of their wired FIOS system and why they are working on a FIOS IP TV solution? Sure sounds like it to me.

What do others think? Is it really possible to run a full blown cable system over 5G and provide high speed Internet too?
