I am asking this because there may be some Optimus Nvidia updates before next year April ubuntu release and i read somewhere its connected with 1.13 features? Or i am maybe wrong.
Given that Quantal ships with Xorg 1.13 RC5 it is likely that it will ship the final X 1.13 version.
Even if it does not ship the final 1.13 (which is very unlikely), you won't have to worry about missing PRIME features as these are already merged with rc5.
