I mean, conduit is cheap and no one has ever been upset when they need to pull an unanticipated wire and didn't have to wreck into a wall.
If you are doing this, run two conduit from the tv to the shelf/stand/whatever where your components will be. Will give you plenty of room for signal separate from power.
Whatever 5yrs brings, your current tv will still probably work and you will still need to plug that bitch in.
