Neither one of these new transmission types is very new. In fact, Leonardo da Vinci conceptualized a stepless continuosly variable transmission already in 1490(!) and the first patent for a toroidal CVT was filed in 1886.

I personally believe that automatic transmissions will replace manuals as the standard choice. Just like Snake, I also believe that at the same time DCT and CVT will force the conventional automatic aside but unlike Snake, I think it will happen relatively fast. DCT will be the sporty alternative for powerful and dynamic cars and CVT will be the cultivated alternative used in the comfort oriented cars. Manuals will propably only be used in some sports cars.
