It is all old story and will be forgotten in quick time. The cricket fans may not be happy with it, but as per the official records England are the world champions. And the thing to remember here is that New Zealand players never protested against either the rule regarding the number of boundaries or the decision by Dharmasena to award the overthrows. They were not happy, but refrained from protesting, taking in to account the spirit of the game.
For many of the cricket fans (including me) what happened during the final was a sham. I believe that New Zealand were the real champions and not England. But after a while all this will be forgotten and only the records will remain. As per the official records, England are the champions and New Zealand are the runners up. And this is what going to matter in the future.
