As others have pointed out, it doesn't matter how much they can produce ps3's for today, because there are still ps3's in the channel from shipments made back in march or earlier. All those ps3's made at a higher price point have been increasing in cost to sony because they haven't been sold, and dropping the price now just increases their cost even further.
If they made a ps3 for a cost of $800 back in mark (theoretically, I have no idea the actual cost) and they expected it to sell for $600 then they were only losing $200 on it (still pretty extreme if you ask me). If they cut the cost now, that PS3 will still have cost them $800 to make, even if they can make them for $600 now, and on top of that, those older ps3's have been costing them extra money for storage at warehouses or whatever, the cost of taking up room someplace. I'm sure they haven't convinced stores to buy all those ps3's and store them at their own cost for 3 months.
Anyway, any price cut they make would have to include those factors as well, not just the cost they can produce a PS3 at today. Based on the numbers released by Sony at the end of march and the estimates for sellthrough on this site, Sony has somewhere between 1.5-2 million consoles produced way back then at a much higher cost than they can make them today.
Personally, I think they are between a rock and hardplace. Damned if they do, damned if they don't. No matter what they do, someone will be pissed about it, either share holders about the increased losses, or the gamers and developers because there was no price cut. I'm glad I don't have to make these decisions =).
