PS2 Games To Appear On The PSN Store- Says The Sixth Axis. Rumours of PS2 backwards compatibility already added in secretly to firmware 2.20 etc… Eventually, all’s I want is to be able to put in PS2 discs and play them on my PS3, just like my friend who has a 60GB PS3. Damn you! Anyhow, read the article on The Sixth Axis and decide for yourself. I’m taking this one with a pinch of salt for now.
