I've never quite understood this argument.
A staggered launch is a meaningless qualifier to use. And is only relevant if it can be shown that they had the stock to meet the demand of a global launch.
Another way to look at it is like this. Between March and September, 2000 sony shipped ~7M PS2 in Japan alone. In the first 6 weeks alone of the PS4 sony shipped(and sold) over 4.3M PS4s in everywhere but Japan.
So lets flip perspectives a bit... If sony had a global launch of the PS2, there is NOTHING indicating that they would have been able to make anything more than the 7M PS2s they shipped in the first 6 months of the PS2s life. At the end of the day, all that really matters is how much of a product a company can make and not where they are selling it or not.
Obviously a company is going to plan production differently when they launch in just 1 country vs launching in 50+ countries.
Global (or semi-global) launches did not become common until the 7th gen and that needs to be factored in when comparing launch aligned sales, it just doesnt make sense to compare the sales of 1 country to 50+ countries.
You are still ignoring the main point and basing all you ae saying on ifs and maybes.
Back in 2000 PS2s were "made in japan" and no one simply had the manufacturing might that companies like Foxconn (sp?) has brought to the market. It makes zero sense launching globally if you lack the means to make enough consoles. You simply DO NOT know if sony would have been able to make more than those 7M consoles they made in the first 6 months being that even when they released everywhere else they were still stock limited. I mean they had only like 300k consoles for the japan launch back in March 2000.
What we know is that back with the PS2 sony managed to make and ship ~7M consoles in 6 months. With the PS4 in 2013/2014, they were able to exceed those kinda numbers in 2 months. Different times. It's not like if sony could have made enough to manage a simultaneous launch they wouldn't have... they just couldn't.
I don't believe this, what do you really think is more important? Being able to make and sell 4M consoles in 6 weeks? Or where you sell those 4M consoles in?
You are here saying obviously company will plan this or that, so what does that mean? Sony planned to not meet their maximum market potential with the PS2 and release in only one region first? lol....
