There is one issue that has not be made clear yet, the ability to play used games on the PS4. On 2/21 Sony Worldwide Studios President Shuhei Yoshida told
Eurogamer in an interview that used games could be played on the PS4. Now fastfoward six days and PlayStation UK boss Fergal Gara says Sony's stance on second-hand games working on PlayStation 4 'isn't clarified just yet' in his interview with
NowGamer .
