Bakkt will probably not be any type of savior. They are offering a one day physically settled BTC future as their primary product. Their goal right now is to get the simplest form of a typical ICE future (they are owned by the ICE, they tend to do physical futures) functioning and regulated and then work on scaling up.
They won't make any actual impact anytime soon, however, the products they are trying to bring up could amount to some small positive sentiment as a signal to the ecosystem about how the US securities and futures regulatory bodies will handle crypto.
