What I expect is Type-A will continue to exist and be implemented into perpetuity because it is the characteristic USB port that literally anyone who has touched any computer or USB device can instantly identify. There are also legitimate benefits to having physically large connectors and ports such as structural robustness and ease of handling among others.
Meanwhile I expect Type-C will supercede both Mini and Micro Type-Bs as intended leaving USB with Type-A and Type-C, a situation similar to today except with one less connector type to worry about.
Universal? Hardly, except maybe being universally recognized by everyone.
