A subtle spec upgrade over the last few months has made unlocked more usable RAM for developers. That may not mean much to you, but it's good news for uber-huge games like the 35GB God of War.
PlayStation University spotted the subtle shift in usable memory, pointing out that the operating system's memory footprint dropped from 120MB to 50MB. Joystiq got in touch with Sony Computer Entertainment's Patrick Seybold to find out what was going on under the hood:
"Since the launch of the PS3, we have been continuously making efforts to reinforce our support system to game developers, allowing them to express their creativity freely on the PS3. As part of this support for game development, the size of the PS3 OS memory footprint has been reduced through network update for the game developers."
In other words, rejoice ambitious PS3 developers. You now have 70MB more to play with.
