Ya know, every time I walk into a chemist, there's a shelf-load of Gillette razor blades sitting there. I guess Gillette aren't selling any blades at all. Similarly PS2's are always available. I guess Sony sell none of those either...
But these blades aren't much anticipated, they didn't have people queuing around the block for them, nor is there precedent for them remaining scarce on the shelf this long after launch. No one is saying Sony is selling no PS3s either, but what some
are saying is that this console that was reduced from 4m to 2m to 1m units, which should be flying off the shelf as soon as they're put there, is taking longer to shift than anticipated.
That would be a bonus to determine how much demand < shipped, but not necessary to see if PS3 is selling okay or not. Shipped covers released to distribution channels (left factory) and not arrived at destination, so this early on you might even have 10% discrepency as a boat-load of PS3s is heading out. Thus shipped versus sold isn't a real indicator either. Shipped will always be higher than sold, and unless you know the ins and outs of the distribution network, you can't derive from that how much stock sits on shelves not being bought.
The presence of stock on shelves is more indicative of a healthy resupply channel balanced to demand, and with no crazy buying frenzy where people buy something just because others are buying it without knowing whether they want it or not. As I said, earlier in this thread I believe, if we expect the US market to lap up 3 million PS3s in the beginning without question, that's only 1% of the population. That means only 1% of customers to a store are interested in buying a PS3 just now. The moment PS3's are put on a shelf, you can't expect all that 1% to be in the store waiting to get their hands on it. Not every one of those is a die-hard shopper who's desperate to get one ASAP. A good many want one, and will buy when they see it, rather than go hunting for one. Now there is a market phenomenum that people buy something because it's popular, and the moment you put one on the shelf people buy it just to be sure of getting one. Those are the items that stay on shelves for all of 2 minutes. Obviously Sony would have loved that, but at this price-point it'd be quite a reach to expect PS3 to manage that.
Understood about shipped vs. sold. Still, taken in isolation, don't sales numbers mean very little? If this months NPD figures say Sony sold 400K, but, for instance, they shipped 500K, you may think "that's a good result" assuming as you say, some are in the channel etc. However if they shipped 1M, that's not so good. If you don't have that number, you can't guage just how well it's really doing.
Also I consider your logic flawed in terms of how many interested people there are. For a start, your example assumes 1 store per person. In reality, a person will visit many stores. Also, you make it sound like finding a PS3 is a random encounter, people who want one will not wait to stumble upon on one, they will actively look for it until they find it, so a store such as Walmart may see, for example, 1,000 people come in per day of which 10 would be interested in a PS3 in your example. I would contend that some shoppers will be exclusively looking for a PS3 and there will be 20 or even 50 people interested, not 10. If this were true, PS3 would be selling those 20 odd consoles we're hearing about, even if you were right, and it's 1%, in 2-3 days they should be sold, but there are reports that they're not.
I agree with Patsu, i'd like to see what happens and will wait for the official numbers, it just seems a little odd compared to a historic launch. Maybe XB is right and it's an anomoly
