Regarding the 40GB being 65nm, I suspected that a long time ago and well before I read this, but I consider this to be a nice confirmation:
My expectations for the 40GB PS3, tech-wise, are as follows:
- 65nm CELL & RSX.
- Southbridge integrated into RSX, no longer SCC.
- Less expensive PSU and cooling solution as a consequence of this.
- Bluetooth+WiFi single-chip, ala http://www.broadcom.com/press/release.php?id=95762
If they also got rid of the GS, then this would reduce the number of chips in the current PS3 from 6 (CELL, RSX, SCC, (EE+)GS, BT, WiFi) to 3 (CELL, RSX+Southbridge, BT+WiFi). At the same time, the amount of silicon should go down by a good 50% (40% smaller RSX/CELL, redesigned Southbridge & BT+WiFi).
If you estimated the bill of materials based on this, maybe you'd even start pondering whether Sony is gaining money per unit! Of course, there is plenty of amortization to be considered here so we'll probably never know since it won't show directly on their financials...
But either way, if you believe the original iSuppli BOM estimation back in 4Q06 (and I kinda don't, but meh), you'll easily notice that the vast majority of the costs are gone. The logical next steps to reduce costs would be redesigning the form factor. Or, alternatively, do the steps I gave above if I'm wrong and they haven't done them yet, such as integrating the Southbridge

That I could say.
