I have been recently investigating this, as having just demo-ed a TFight 305, and falling seriously "In love at first hit", I am about to transition from being a Pure Drive user (over 10 years) to Technifiber (TFight 305).
Technifiber are apparently going to making a "Major" announcement which insorporates another well known Global brand, and releasing a new TFight range from Jan 1 (available in Europe by end of Jan).
I know nothing about any change in technology, etc. but for 100% sure a new TFight range is being launched to the market around the Aussie Open time frame.
I too am wondering about waiting for 2013 Models, but I have really clicked with the TFight 305 current model.....
