Paddy, does your friend work for Sony or is he just an enthusiastic amateur like ourselves? Not pulling down your source, I am so thirsty for solid knowledge on these things it scares me. I had read all over that the PS4 will have 4GB of fast RAM, but the Xbox will have 8GB of slower RAM. Now if Sony did double the faster RAM they would have a beast of a rig.
I will be getting the Xbox, so I am desperate for it to be on the same level as the PS4. Not seen many credible rumours that the Xbox will be more powerful though, which disappoints me a bit. Lord I hope they don't bog down the dashboard too much. I find the current one has just broke the limit, the thing is so slow now.
Backwards compatibility is not something I have ever wanted, until now. I only want it for my downloaded purchases though, like the Arcade games. Would be a shame to lose them.
