Well I think that's the idea not to have to rent their cable box to save money.
Xfinity is already doing this with the Roku. I found this on their site.

Frequently Asked Questions (FAQs)
What is the Xfinity Stream Beta app on Roku?
It's a new app that is in Beta trial that allows Xfinity TV customers to access their Xfinity TV cable service, including live and On Demand programming as well as cloud DVR recordings, on a Roku streaming device or Roku TV.
I think with Amazon being the provider for the FireTV/stick I would say it would be supported
ln fact maybe better than the Roku since Amazon is most likely in a better financial position.
COX has always been behind the 8 ball concerning new ideas maybe some greed too.
I think the future of cable will be via the internet using streaming boxes. Competition
can kick in and pricing will change. There are several companies now selling programing
and more to come. COX at some point will have to throw the towel in for the streaming boxes
or loose customers. As it is now with a FireTV or Roku you can download many of the popular
app like Showtime, HBO, EPIX and more provided you subscribe to them. They also
work anywhere there is internet.
