This article is wrong, it's not the latest mobo revision, the latest one has the wlan/bluetooth integrated into the main board. Below you can see how the latest one compares to the original one. 
Below from left to right is a) the original mobo with wlan/bluetooth board, b) is the previous mobo mentioned in the article above with front and back of wlan/bluetooth board, and c) is the most recent mobo with integrated wlan/bluetooth board.
Smaller, cheaper but not small enough for slims
The size of the board isn't a problem for creating a slim PS3, the board is as slim as it can be already, what really needs to be shrunk is the cooling system. This is dependant on the size of the CPU and GPU dies. Sony are set to start production of 45nm Cell this year.
Below you can see how much the heat sink was reduced from the original 90nm CPU/ 90nm GPU through 65nm CPU / 90 nm GPU, and 65nm CPU / 65nm GPU.
Furukawa Electric Co Ltd exhibited a new heat sink for the PlayStation 3 (PS3), a game console developed by Sony Computer Entertainment Inc (SCE), at Techno-Frontier 2008. The exhibition took place from April 16 to 18, 2008, at Makuhari Messe in Chiba Prefecture, Japan.
The company defines the first heat sink mounted in the PS3, which was released in November 2006, as the first-generation product. And it already begun commercial production of the third-generation heat sink for the PS3. The third-generation product is characterized by its small size, light weight and low cost.
The heat sink developed by Furukawa Electric is used to cool the microprocessor "Cell" and graphics LSI "RSX." When Nikkei Electronics Teardown Squad disassembled the PS3 in November 2006, this heat sink, together with a large cooling fan whose diameter is more than 13cm, drew its attention (See related article).
The PS3, at first, is equipped with the Cell produced in 90nm process technology. But it was replaced with the Cell produced in 65nm process technology to reduce the cost and power consumption. Along with this change, Furukawa Electric reduced the size, weight and cost of the heat sink by, for example, decreasing the number of its components each time its generation changed.
Especially, the shift from the second generation to the third was drastic. In the first and second-generation products, a large heat sink cooled both the Cell and RSX. But they are cooled by separate heat sinks in the third-generation product.
Furthermore, copper heat pipes, which were used in the first- and second-generation heat sinks, are no longer used in the third-generation product. Five and two copper pipes were used in the first- and second-generation products, respectively. Furukawa Electric realized enough heat-radiation performance without using a heat pipe, the company said.
The first-, second- and third-generation products support power consumptions of about 200, 160 and 130-140W, respectively, for both the Cell and RSX.
The kinds of components are more than 20 for the first generation and about 10 for the second. But the third-generation product has only three kinds of components, a fin and pin made by aluminum and a thick aluminum plate used as a substrate. As a result, the weights of the first-, second- and third-generation products are about 700, 500 and 350g, respectively.

Sony shrinks Blu-ray laser
25th January 2008 12:16 GMT
What do you get when you cross Sony with Japanese laser specialist Nichia? The answer’s a tiny blue-laser data reader module that paves the way for slimmer, cheaper and portable Blu-ray drives.
Sony’s new laser unit measures 14 x 7.4 x 3mm and is expected to be built into slimline Blu-ray drives that can be fitted into skinny laptops, in-car entertainment systems and handheld disc players, although it hasn’t mentioned anything about introducing the laser to Blu-ray drive in the PS3.
The module can read dual-layer Blu-ray Discs, but it's not capable of forming the basis for disc writers.
Mass-production of the laser is expected to start sometime this year, Sony said, but the electronics giant wouldn't reveal when it expects the first Blu-ray products featuring the new laser to become available.
