The UK and most of the EU are usually left behind when it comes to the PlayStation consoles. They usually launch in Japan first, then the US, then a few months later in the UK.
But Sony have confirmed in the form of an advertisement that the PS4 will definitely be coming this year, presumably around Autumn or just in time for Christmas. The ad was found in the latest copy of the Metro newspaper.
You can clearly see in bold writing that it's coming in 2013. Myself and others in the UK will be pleased that it's coming to the UK at the same time, no having to wait in envy of US citizens.
E3 will be the event where Sony will show off their PS4 hardware and everything else they can.
