well i don't know,what u reading but .
sony and microsoft sign deal with amd to give/make gpu to power next consoles
ms and nv again in gpu deal LOL
they are in war since xbox (no way ms will use nv crap in consoles ever again

)
and me think 1 partner is qualkom (they use ati gpu's in it)
and in spring they will have 28nm 4core soc,nv 40nm

second samsung or ti
for nv lovers ,nvidia wasnt use 28nm for tegra3 beacose they dont know how ,so tegra 3 40nm ,tegra 4 is tegra3 on 28nm
tegra 5 is arm v7 prolly ,tegra 6 arm v8 server in 2013 winter
and qvalkom say thay will have v7 in winter v8 spring 2013
btw v8 is monster compared to these arm soc today
64bit ,designed for xx cores (10+),better memory link
etc
if i am ms this baby will be in my console
10+core on 28nm later 20nm (20-50$)amd gpu core on 28nm (50-70$) later 20nm
4+gb memory 1+gb gpu memory (50$)
with full dx11/opencl support (open cl is free for all cuda)
and all together around 300$ compared to xbox360 800$
