I called PSE today to check on my new tac replacement and I was told it ships monday,I can't wait to get it. So I asked about the NEW 2013 Tac 15 Elite, He said that the cams were upgraded which will help with preformance and you will gain a couple of feet faster. He also said that the cranking mechanizm will be internal which give PSE a chance to use larger bearings on the crank. Does anyone have any other info besides it shipping in Jan?
