PS3 gave back 70meg of ram around the time god of war 3 came out
PSP gave back 100hz more processing power as well

Its standard for consoles since the PSP, (Those that get firmware updates) for reserved resources to be reduced as the OS footprint reduces through the consoles life cycle.

It did not happen on cosoles before this, because there was no way to update the OS.

Thanks.

They  sound more like optimisations rather than actually holding back the performance of the system on purpose which is what CDiablo kinda alluded to. Maybe I misunderstood.
