I personally haven't bought the program but l have looked at the program and the theory behind it. Basically its a periodized program that prevents its users from hitting a plateau by using different hypertrophy techniques. Most people only know a few techniques like time under tension and volume but in reality there are more ways to build muscle like max intensity, frequency, workout density and many more. Towards the end, there are specialization phases for different body parts like chest, Quads, etc.
To answer your question, every product has a bit of hype, that is normal internet marketing tactics at play but in my opinion this is quite a unique product because of all the hypertrophy models that are incorporated and people don't have the chance to stagnate so results are easier to obtain and more predictable.
