I have to say though Acert that your conclusions stem from adjusted analyst numbers, numbers that in my opinion are flawed from the start. I think if we were going to do the PS3 price/component thing, it'd be better to start with the only arbitrary constant we know to be true, and that is what Sony was willing to sell the PS2 for. Since we're talking US prices, we'll use the US launch.
Here goes some 'speed' math.
Ok so PS2 launched at $299. What are the differences between PS2 and PS3?
EE ---> Cell ; My own theory is that Cell is less expensive than the original EE
GS ---> RSX ; Again, RSX shold be cheaper. In fact, a good deal cheaper if it's more or less a G71
Backwards compatability though
seems like it is going to make use of a full EE+GS (unless anyone has any theories on this), so for chip costs I'm just going to round and call it even between the launch PS2 vs launch PS3.
Now, Blu-ray vs DVD. I'll add an arbitrary $100 to the price at retail like everyone else is doing.
HDD. Ok, an arbitrary $50 at retail assuming it's actually included in the system.
And all that HDMI, I/O, royalties and junk like that - I'm throwing in for free - it's probably like a $10-15 difference from launch PS2s anyway.
So that's how I reach a super accurate $450.
I mean the reasoning is cheesy as hell, but still I think using as a base a system Sony has already launched, we establish for ourselves a floor of where Sony is willing to price. Blu-ray could be a larger variable than above though - honestly in either direction depending on Sony HQ's willingness to subsidize - and it assumes also global subsidization of the US product similar to PS2.
PS - Using the same 'logic' as above I'll put $499 as a backup price, as I could see the EE+GS and I/O crap possibly tacking on another 'unit' of price, which for the purposes of this poll seems to be $50 increments
