Highly unlikely, the totality of what we've seen in Dragon Ball Super has been from Age 778 where Battle of Gods takes place until presumably late Age 780 so it's a span of three years up until the point we're at in the manga. I don't see them doing any large time skips just to jump to the end of Z portion. They still have a lot of wiggle room and whose to say that Super ends at the same time the 28th tournament takes place? Ideally, Super runs into the end of the original manga and we get a bit of a time skip and then it picks back up. Whether it's called Super or something else. Keep the party going!
