A little correction if I may,

Jeet Kune Do is the art of fluid movement. It is the art of shedding all forms and taking on all forms at the same time. Direct line to the target, the most effiicient form of fighting. It has lineage toward Tai Chi Chuan.

It is not at all about “visualizing where your opponent will go next, and trying to beat him to the punch” that’s actually quite impossible. Yes, anticipation is a part of it, but it’s every martial art teaches that. It’s actually about reacting in the most direct manner, not adhering to any forms or styles, but doing the most efficient movement to counteract and act.
