FireTV/Firestick/Roku app coming?

This appears to already be in place with Xfinity.  You can download their app from Roku and watch TV without the need of a cable box saving the customer the rental fee

and another box to deal with.

Just wondering why COX is still lagging in technology with this?   Its the future to stream and get rid of those expensive rental fees which is sort

of insulting to charge someone a fee for a box in order to watch cable tv which they already have to pay for.

Can I get an update ?

thanks,

Ken
