Some people will get rich, but not too many because once the pricing model is released everyone can jump in and do it and there will not be much advantage to be taken.
Also, such of a pricing model would probably only able to approximate the price. One pricing model that I admire the most, for those who are interested, is the Black/Scholes Option Pricing Model. It prices the fair value of an option. It is accurate because if you run a simulation with 5,000,000 or more iterations with simulated stock price movement, the result would approximate the formulated price to the penny. The model was built by finance PHDs and one of their wife who happened to have a PHD in physics.
