According to the link below (thanks Scoob), Sony sold roughly 3x as many ps2's at or below $200 in the US than above that price over the lifetime of ps2. Which breaks down to roughly:
25million @ <$200
8.5Million @ >$200

higher priced sales -
With 360 selling the way it has in the states (~1.7 million) at a $300-400, the market does show some flexibility with early sales acceptance of higher prices, but sales are starting to become sluggish due to the relative software drought. Ps3 may be faced with a similar situation come this time next year.
Price drops -
Xbox1 trippled their sales figures when dropping their price to $200 as did ps2 in the following couple months. Some of this I'm sure is fueled by the price being just flat out cheaper than launch as it makes those that have waited, feel that their wait was somewhat worth it, but we(I) don't have a historical figure of a successful machine launching at anything more than $300. Sony may get these same sales jumps from dropping to $400-500 and $300-400.
Gifts -
One other interesting tidbit in these numbers though. You'll see that there is a
vast sales peak once a year, every year for every machine in the list, Christmas. This means a very large chunk of these sales figures is parents/family buying these machines for gifts. There are sales at other parts of the year to but they are significantly overshadowed by "Under the tree" sales. When one factors this into the pricing equation it becomes apparant why this sub $200 price point is so important as a "gift" over this price becomes more and more difficult to justify no matter how much Johnny cries for his favorite toy.
Cpu -
Cell and xcpu should get some help with a move to 65nm late this year/early next. considered with mass manufacturing and ironing out the process the chips should cost 75 - 50% of what they are now. Cost unknown.
Gpu -
Same as above ^
Ram -
With ps3 using 700mhz gddr3 as well as 360 this should drive the price of that component down fairly quickly. Rambus ram is an unknown as there is a royalty attached to the raw costs but should come down in cost with Sony's vast orders. Cost unknown.
Hdd -
Cost should remain fairly constant above $30-40 through the lifecycle unless replaced with flash drives (cost unknown).
Dvd/Bluray
Dvd should remain fairly constant around $30 with Bluray dropping with mass adoption. Cost unknown but should be bottom limited similar to dvd +/- $10.
MB
ps3 motherboard is slightly more complex with both a rambus bus and gddr3 bus along with most other componentry being the same as 360. Cost unknown.
Misc components
Cost unknown.
I'm sure I'm missing a few things and perhaps you guys could help fill in the blanks.
My guesses:
PS3 if maintaining same specs as the $500 unit - it looks as though May, 2008 would be the earliest they could hit $200 based on a 65nm die shrink followed by a 45nm die shrink ~18months later. This is assuming Bluray adoption rates are high along with ps3 component sales up to this point. Realisticly I would say they would be comfortable hitting $300 at this point and $200 at this time the following year in 2009.
360 maintaining the same specs as the $300 core unit should be able to hit $200 by May 2007 (based on ps2 dropping to $200, 18months after a $300 launch).
