With companies such as Wilson, ProKennex, and Yonex all coming out with new player's racquets.....anybody know whether their previous frames will be discounted anytime soon? I've heard Wilson is coming out with a new player's frame. In addition, ProKennex just recently released the Redondo 100% graphite frame, and Yonex has a new player's frame as well which Hewitt and Nalbandian are playing with.
