PS5 120 million units to be shipped within 5 years, according to supply chain source.

Waaaay to early to tell how much PS5 is going to sell in its lifetime but I can comfortably predict it won't do 120m in 5 years, let alone 170m. PS4 had all the stars aligned to get to 112m in 6 and a half years, PS5 is not gonna achieve 120m in 5 years.
