I spoke to someone at Prince directly and my 6-month warranty T-22's will ship from them on Dec. 16th. Seems they were on backorder.
Not sure what Prince's plans are for the 22's going forward, but I just saw a photoshoot on facebook showing Isner playing with some custom colored t-22's. Seems like Isner is signing with Prince for 2013 - at least for racket and shoes. Not sure if he's staying with Lacoste or not.The guy at the Prince Warehouse said he is been seeing all sorts of new stuff for 2013... no details for me yet though.
