Now that Murray has a slam, plus the gold medal, expect his confidence to finally be at its highest ever. The "Big Four" is now actually that. I was hoping Murray would win Wimby or the Open this year, before Fed gets to his twilight years, and now that it's happened, I get to make this prediction: I expect the Big Four to be the most dominant it's ever been come 2013, bar a prolonged comeback from Nadal. We could see chalk in all the grand slams semi's next year. It will truly be a shootout for Slams next year.
