The cork should be on its way out, but if it is, it will be really slow. The better technologies (screw tops, bag in a box) are associated with cheap wines. It will be a long time before any substantial number of $20+ wines use them as a result. The wine makers would quite rather 10% of their product go bad and have to be refunded than have it be thought of as Franzia. (I have seen a lot more synthetic corks popping up, and this product might work with those.)
Depends where you live. Here in Australia twist top is king. Most bottles you buy that are <$40 from 2011 onwards are twist tops (excluding carbonated, people like to pop the cork even if it's a synthetic one). In recent trips to the US I've noticed that it isn't as popular. People there seem to think twist top is cheap or tacky.
It's the same with beer and cans.
