From that article:
So basicly they tried a JIT distribution at launch which failed badly. Luckily for them they were launching unapposed, a luxury neither will have this time.
A JIT distribution does work though, eventually, so what's needed is a bigger initial launch cache. IMO to feed a WW launch, there'd need to be double the 3 mil MS tried with the 360. With a production capacity of 1 million per month, to build up the requisite cache would be 6+1 months or a production start of May for a November launch. If you wanted to supply each of the 3 regions an additional 1 mil units in 30 days after launch, you'd need an additonal 2 months or a production start of March. That's next month!!
Nah, 2 million for November-december would be enough to do a decent launch worldwide. Basically Wii U sellthrough
Sony first announced worldwide launch for PS3 but had to cancel it for some yield issue. Even Japan+Usa was still limited
