Sony has released a fairly comprehensive Q&A ahead of the launch of PlayStation 4 next month (November 29). In the post there's details on the console (performance, resolution, disc drive, hard drive etc.) and accessories (controller, PlayStation Camera). There's also a few details regarding PSN (for example, you can have up to 2,000 online friends as opposed to the 100 you could have on PS3), launch titles, used games, backwards compatibility. Most of the information held within we already knew, but it's nice that all the details collected together.
