Contrary to previous reports, PlayStation Europe CEO Jim Ryan recently stated to Eurogamer that PS4 will probably arrive at the same time as Next-Gen XBox and Nintendo consoles.
To quote: "I think we would consider it undesirable to be significantly later than the competition [with the next PlayStation]."
He also noted, however, that there is still a lot of life left in the PS3 and explained:
"If you look at PlayStation 2, now in excess of 150m units installed globally, a huge majority of that was done at price points of £120 or lower.
We've only just hit £199 in the UK [with the PS3] so clearly there's a considerable untapped part of the market there."
