There's an easier explanation to why PS sells so much. My question is switch sales seem too low and should have grown year over year like everywhere else. PS sells more because Sony did better marketing to establish itself and it has a better distribution network to reach all the countries in Europe whereas Nintendo does not. That is why Nintendo also suffers in the rest of the world. I'm saying your analysis is thoroughly and completely wrong in my opinion and that is corroborated with the fact that distribution of age groups of ps4 and switch buyers is very similar, not different. I'm also saying that I think the switch is selling much higher than what is shown here. That's my point, nothing else and it's based on looking at trends in japan and US. Europe has no reason to provide no growth year over year to the switch sales, it's just inconsistent with everything else we know. Europe should be anywhere from 70,000 to 85,000 weekly by now, not around 65,000.
Different regions have different sales curves. Look at the data Nintendo gave in last quarters financial presentation.
Japan, +4% YoY
North America, +18%
Europe had huge growth last year while Japan was minimal and N. America was moderate.
Notice how Japan had the smallest growth in 2018 but the highest growth in 2019? It had more room for improvement while Europe had large growth in 2018 so its room for improvement is lower this year.
PS4 sales in 2017 are another good example. This was the year where PS4 had its global peak, up 2.7m YoY, but NPD+Media Create actually had it slightly down about 300k YoY. This means that US+Japan were down 300k while Europe+RotW were up by 3m.
Just because 2 of the 4 regions are up/down, does not mean the other 2 will follow the same trend. Switch could very well be undertracked but your reasoning behind it is flawed.
When the herd loses its way, the shepard must kill the bull that leads them astray.
