I just heard from a friend who maintains the bricks in the Walk Around the World that it will be removed in about 6 - 12 months. Apparently they have already stopped maintaining the bricks with the exception of keeping them level and smooth for walking on. The areas where the bricks are present are to be resurfaced presumably with pavement similar to what surrounds them. I know that this has been talked about for a long time but it sounds like there finally going to do it.
