Well, there will be changes. The changes wont be so drastic as to change the essense of the game. This is why I believe the Flagstick rule will be changed. For the amateur player, who cares if the flagstick is struck while putting. For the elite level, I can see that it wont change much since they have caddies that take care of the flagstick.
SO again, changing this rule will not impact the essence of the game.
Finally. I've personally heard this more than once and now someone who was at St-Andrews heard it first hand from some committee members . I don't see what there is to gain by saying this if there arent any rumblings about it.
