Yes, having won it twice, James is looking at new challenges, although if Kristof had been up for a showdown he would have entered. If Kristof had more of an ego he might want to beat James and show he was still the best, but I think he is pretty internally referenced!
Good that Matthew is coming back. He'll be a contender (if in good shape, etc) . Bjorn should be quicker based on last year's form but can't afford to screw up his routing again if he is close behind!
Who else has said in public they are not riding / didn't get a place?
