"In fact"If Wilson has this(profit) in mind, they should release the exact same model Roger uses because there will be huge demand for this racquet, I can assure you. They don't even have to do any more marketing/advertising because it has already been done during the past half year. Once it is released, it will sell out in a few weeks. It will be hard for Wilson to meet the demands, in fact.
Most people have thought they were getting the racquet Federer has used from the beginning. The average consumer thinks they're getting the same racquet that they're told that player plays with. It doesn't matter if it's the actual racquet or not. The average consumer has no idea they're getting a paint job of pro players' racquets.
So no, Wilson knows what they're doing.
