Why would Sony put a GPGPU into a gaming machine? As Kepler has shown there is a big decent performance advantage in stripping that stuff out.
-The 7870/7850 & 7770/7750 have a lot of the GPGPU functionality (notably DP performance) of the 7970/7950 stripped out. In all likelihood this will be a custom designed GPU/CPU combo anyhow (much like the 360's Xenos CPU was some freakish middle-ground between the X1900 and the HD2900). They're saying southern islands only because that will be the base this GPU is derived from, probably with all the GPGPU stripped off.
What would be far more interesting is they leave it in, with the express purpose of leveraging it for game physics and AI etc...
