It's great that the Pi is selling, the whole goal is to get them into as many people's hands as possible. But my point is that production needs to be increased. The foundation doesn't really gain anything with people buying from overpriced resellers. In fact, there would be more sold if there was stock always ready to ship at the base $35. I know, it's mostly a US thing to with the prices, but not enough people are given the chance here to buy one for the official $35 price due to low stock.
Last I heard (I asked Eben at the Maker Faire if my guess was correct, and he said it was) sales are over 6 million. In February, it was stated that production was running at 20K per day.
So far as I can tell, if the Sony factory wanted to increase the production rate, they'd have to add additional assembly lines. That would mean buying additional equipment. That in turn would mean that they would have to expect to have enough production orders over the life of that equipment to make a profit on the purchase and operation of that equipment.
The problem here is that no one really knows what the lifetime sales of the Pi are going to be. Every bit of plant expansion is a gamble. Gambles like that have to make it past the "bean counters", and group notorious for aversion to risk. The good news is that sales of Pis haven't shown any signs of slowing down...so far. The bad news is that some day it will. The trick is to figure out how much plant equipment can be paid for without adversely impacting profit before the sales flatten out.
Anybody got a working crystal ball?
