Well next year my family might be getting a HD TV and a blu-ray player. So I talked to my dad and I said why don't we get a ps3, I'll pay for half of it, and he said yes. It is not definite but still, I can hope.
So Which version is $400 and Which versions are backwards compatible? Also I heard some don't have Wi-fi (Which ones?), and can you get online any other way?
Also how much memory do you really need anyway. . .
