I'll just go ahead and make a guess here:
My guess is that the successor to AMD's Hollywood gpu will be very similare in arrangment and clocks to the 6450: namely that it will have 2 4x4 blocks of superscaler units, as compared to 3 in the xenos (or the 24 in the radeon 6970), but it will be clocked alot higher, at 700~800mhz (unlike the 500mhz xenos). In terms of performance, that will get it within spitting distance of the xenos, but with far fewer transistors, making it more practical to manufacture in volume. Also, I will guess that it will be made on a much more "mature" lithography node: say 65nm, maybe 55nm if there is enough fab capacity available at that resolution.
