I hear you. But the point of them shipping less units at higher prices (and therefore margins) is that they don't see it as a lost sale.
I mean, if it was £649 and we assume the cost was (for argument's sake) 50% of that, then selling at that price they make £325. But if they sell it at £1200, they make £875 instead of £325. i.e. nearly 3x the profit, so they can afford to sell (roughly) one in every three units that they would have at the original price. If theyy make the same profit on one that they would have on three they can "lose" two in three sales without losing any profit.
Tha's a hypothetical example, obviously, as I have no idea what their margins are. If they make only 10% margin at that £650, then they can "lose" 9 out of 10 "sales" at £1200 without dropping profit. Or sell 20% of the volume, and still double their profit.
My point was that if that's how their numbers work (and nobody except top management is likely to know), why wouldn't they? It's bad for gamers, but great for their profits ... as long as enough people keep buying at that higher price. So far, it seems they are.
