I'm pondering what's the best approach to size the market for Sony's Playstation 5.
I assume it's the global market.
My initial guess would've been to go via # people having PS3/4 and replacing with PS5 + # new customers (by age group ~14-30). But this leaves me with estimating the current PS3/4 market, which makes it a circular problem.
Any hints would be greatly appreciated!
So I take your approach to estimate PS4 users and then continue with % replaced per year and % of new user based on addressable population?
