I've been following Zeroshift since it was concieved a couple of years ago. It's a new type of gearbox that could make the DSG obsolete. Thought you guys might be interested, since so many people on this board are looking forward to the availability of DSG on all cars.
Originally it was going to be an after market option for the TVR tremec gearbox, but as interest and investment grew, it is now being developed for F1 teams and and mass production.

The way it works is that it engages two gears at the same time, during the shift. So "Zero" -shift. Unlike DSG, which has a short pauze as it changes between the clutches. Even a traditional sequencial gearbox cuts the power to the wheels during the shift. Zeroshift doesn't. It connects the current gear directly to the next one, transferring all its energy. Then thanks to the sloped side of the "bullets" which connect the gears, the previous gear goes into overdrive, and is disconnected. (the newest evolution seems to use rings instead of the bullets)
I don't have to tell you the performance advantage of a gearbox that wastes not a millisecond, and not a Joule of energy, during the shift. And unlike DSG, it can be easily integrated into an exsisting manual gearbox.
