PlayStation Network activity has returned to 90 per cent of pre-hack levels, Sony Computer Entertainment America President and CEO Jack Tretton has revealed during the platform holder's E3 conference.

Following a PlayStation montage - which seemed to last forever - Tretton took some time to address the PSN outage thanking partners, retailers and consumers for their patience and support over the difficult time.

It is however, the consumers which is of most importance said Tretton, stating that the company does not take their loyalty lightly and is extremely grateful that most have returned to PSN.
