How much RAM does the PS3 actually have? The PC I owned 4 years ago had 1GB. I have 8GB of RAM and 3GB on my graphics card (NVIDIA GeForce 555M GT).

I do think that the PS3 will be limited by hard drive space, but it's a good thing that the developers were able to compress data. If there is every a Wii U version, we can use external hard drives for that.
