Shaun Marsh will come back once he is over his injuries, remember he played during the Aussie home season ODI's but tore a hamstring at the MCG vs SA, then returned in the Pakistan series before the Ashes this year but tore it again, he is very much the 1st choice opener with Watson.
Was the 1st choice opener. White has definitely passed him and Ferguson is taking over the Hussey role so I really don't see a spot for Marsh unless Hussey retires. And even then Hopes has shown he can hit down the order and his bowling is more than handy.
