Just saw an advert for roku 4. features: headphone jack built into remote, cool. find lost remote features - I can see that being useful... amazon prime out of the box, always handy... wait - no reference to 4K? Could it be that roku's bean counters F-d us thier device too? ok, it's got 4K, it's simply a minor line in the spec sheet. I guess that makes sense that a new device designed to be a key hub of the one's AV experience would certainly support 4K, no need to advertise the obvious, right?
