Probably be nearly ten years before the average house is using ten-gigabit Ethernet, and cat 6 cables should be able to handle that at the lengths you'd use in an average house so long as you don't have too much interference (e.g. lots of other cables carrying high-frequency signals nearby). Cat 5e will almost certainly limit you to gigabit though.
For hundred-gigabit we probably are going to have to switch to fiber. But in home use that's likely to be another ten years down the line.
