The biggest problem is that it takes months and millions of dollars to bring up new manufacturing capability. Sure it would have probably been worth it 6 months ago but now, who knows when the demand will end?
Hindsight is 20/20 and had they increased production to meet demand at the beginning it probably would have been a very good business move, but every time the idea is brought up the company has to look at how long they think the demand will be this high. So far it looks like they've been betting that demand would drop before they could get a new facility up and running and have avoided increasing production capacity. They've been wrong, but it's getting easier to find them (I've seen 3 on the shelves now) so we're probably at the tail end of demand, of course if they brought more production online they might be able to meet the Xmas rush, but if they bet wrong they loose all the money spent bringing up a production facility that they don't need. It's a tough decision and I'm glad I don't have to make it.
