Yeah, all this is saying is that Sony won't be building expensive proprietary technology like Cell or Blu-ray, and esoteric technology like XDR Ram, into the PS4.
They probably are going to use off-the-shelf components like MS. Intel, IBM, ATI, Nvidia, all make components that are impressive. There is no need to develop everything from scratch in-house like the PS3. In fact, the MS tactic of using off-the-shelf components (which they have used even on the first Xbox) is clearly the way to go. Outside of a few first-party titles (Killzone, Uncharted,God of War) that look wonderful, most third-party cross-platform titles haven't bothered to tailor their development for the Cell. And as far as the disk format, there really isn't any impetus to go beyond the 50GBs that Blu-ray affords on the PS4.
The real reality is that game development costs are astronomical for AAA titles. Developing for a single platform really isn't viable, especially if they are using an esoteric architecture like the Cell. Its unreasonable to expect developers to give one platform special attention over the other, and in the same respect its unreasonable for a platform maker to build technology that will go unused into their machine as well.
Looking at the NGP, Sony seems to have adopted a plain-jane quad-core ARM cortex-A9 and a quad-core PowerVR chipset. Hardware that will be common place in the next year, Qualcomm's Snapdragon APQ8064 is similar in design, Sony clearly intends on having the Playstation Suite on Android phones converge with the NGP. Sony clearly intends on having the PS4 go a similar route.
It wouldn't be surprising if PS4 uses a ARM CortexA15 (which goes upto 16 cores) and an Nvidia chipset like "Project Denver"; Nvidia ARM/GPU hybrid. So that all development efforts PC/NGP/Android/iOS/360/Nintendo Project Cafe/PS3/PS4 can be brought under one roof. Obviously, the concept of the hardware platform itself is changing for console makers. Cross-platform tools such as Epic's Unreal Engine are becoming mini-platforms unto themselves.
