The same discussion has been going on in a number of forums and my take is that I don't believe it to be a hoax or an undue whinge, nor mindgames but do strongly suspect that the real meaning of the comments have been somewhat 'lost in translation' and would not judge their veracity unless I could see a video of the question being asked (thus judge by tone and body language).
IMO, CS was likely asked a question as to 'how is the wrist' and responded by saying 'it still hurts and is causing me grief, not good really and I expected more by this stage, may as well sit out the year because I cant compete with it in this condition'. On other words, answered with frustration as we often do when we ourselves will respond with a similar comment to 'dont know why I bother sometimes'.
