I don't really understand what you're asking.
Are you asking if they will introduce Heroics with a higher starting level (unlikely, IMHO), or are you asking if they will give everyone a free heroic with the next expac (also unlikely, as they have never done that before).
They have, on a couple occasions, given all subbed accounts a free heroic, but that was usually tied in with Anniversary, or some other event. It's been at least 4 years since they've done that.
