I don't know, but if I did, NDA would prevent me from telling. So, no one with knowledge of such could answer.
Personally, I don't expect Roku to come up with a device that would include a TV tuner. Roku TVs have them, but Roku doesn't build Roku TVs. If they were interested in that, I suspect they would already have that.
Roku is more into services (The Roku Channel, Roku Pay, etc) and advertising revenue (ad-supported Roku Channel, ad network for developers, etc). Investing in hardware would be a large expense and, I suspect, a long time before they recouped the cost. Consider that other companies, such as Air TV and Tablo, have apps for Roku (Air TV via Sling TV) to accomplish what you're after. I don't think it will happen. But, I could be wrong.
