Besides, would there be much of a difference between launching with 200k units and launching with 400k units?
In the end, a very small percentage of the people who want a PS3 would have been able to get one, even with 400k units out. Say, there are 10M people who want a PS3 now, the difference is 0.02% and 0.04% of demand satisfaction. Sure, 0.04% is double, but really it's not a huge difference, they're both tiny, demand would never have been satisfied, so might as well launch even with just 200k units than not at all. The press would have reported huge shortages anyway, whereas another delay would have been on a whole other level of bad PR sor Sony. It just wasn't a viable option for them.
