Just need to look at it from a business point of view. Consider stores that have alot of inventory on NIKE equipment and balls. Nike, is not going to say, you can not sell our equipment anymore. At that point NIKE would have to reimburse every store that has NIKE equipement and balls. And that would not help their bottom line.
When the inventory is gone, which include wholesalers, and distribution centers, these places will not be able to turn to NIKE to buy more.
As for virtual equipment, as long as WGT continues to pay royalties to NIKE on their equipment and ball sales there might not have any issues with WGT allowing them to use their brand. However, there will be no new equipment in the virtual environment.
