Wow! VW are so ambitious. Haven't solve the problems with their 7-speed DSG gearbox, and I heard now they want to develop a 10-speed DSG. Remembered my cousin's VW Polo with manual-transmission which brought over from UK, not that many issues other than the usual wear & tear.
More parts = higher percentage of individual parts failure.
I don't think this 10 speed gearbox is a good thing since you have much more gear ratios to play with, your transmission will definitely shift more to maintain the efficiency in each gear. Since it is shifting more, I think the wear and tear will be faster too.
