FWIW initial retailer profits on consoles are horrible for the retailer close to 0% in some cases
In absolute terms or in relative terms? The 50% profit margin that was presented earlier is a rather optimistic consumer oriented view of what the retailers make. In most cases, they make well over 100%. It's one thing to actually know that retailers only make 1% profit selling consoles, it's something else to know that as far as retailers are concerned 'We don't make anything off selling hardware'. Because to Walmart, making 10% from selling hardware really is 'nothing', because that 10% probably doesn't cover their overhead.
The difference is only relevant as this is a discussion related to BOM and cost/price of the consoles. Walmart might net next to nothing by selling hardware because the 10% doesn't cover their costs. As Sony (for example) lowers their price, if the profit margin doesn't increase for the retailer, then they'd begin to lose money after factoring in overhead.
Clearly, 10% (made up number that we're using) of $499 is greater than 10% of $399.
Because the retailer is unlikely to eat that additional cost, that means that Sony actually has to take the additional loss. Not only by lowering the price, but by increasing the profit margin to the retailers to at least remain constant.
As the product matures though I would imagine that the profit margins increase for the retailer, I have no idea what the current margins are on the various boxes for various retailers.
Yet, I have difficulty seeing how this sliding scale is actually feasible based upon my statements above. As the product matures, the price lowers, so the margins to the retailer would have to increase exponentially and that cost would have to be absorbed by the manufacturer.
Ie: 10% of 499 is 49.99, we all get that. It's easy.
10% of 399 is 39.99. The margin has remained the same, yet the net to Walmart is now less while their overhead involved would remain the same. (Sales force, electric bill, rent, etc.. doesn't decrease when Sony drops the price of the PS3)
In order to make things 'fair' (HA!) if Sony dropped the price of a $499 console to $399, they'd have to increase the profit margin to Walmart from 10% to 13%.
So a $100 price drop doesn't cost Sony $100. It costs them $150.
