By the by Rosberg would set a record of being the first driver to win the opening three rounds and not win the championship. Hamilton moved to Mercedes-Benz at exactly the right time; just as they started designing a winner, new regs or not. I don't think he would have done much better in Schumacher's Merc and his 2009 with McLaren showed how bad it can be for a top driver in a crap car. I personally don't think he would move to Ferrari, or anyone else for that matter, unless he was confident that they were onto a winner. Is he the kind of driver who can do well in bad cars? His early career suggests not but he has matured somewhat since then. But if he did move and Ferrari were still 2nd best and then he wins a title... that would be a great achievement. Something Vettel has not yet done and something Alonso sadly never did.
