The PS4 will not require an always online connection and, it will not block the use of second hand titles.
This was said back in February, by Sony Worldwide boss Shuhei Yoshida during a round table after the PS4 reveal.
Kotaku also reported this back in February but back then it was all rumours now however it's been confirmed by Yoshida.
Any DRM on used games will be left up to the publisher in question, according to Yoshida.
Hope this clears everything up.
So what do think guys now Sony has scrapped this will MS also do this?
If you ask me YES they should.
