PS4 can play used games

Despite a heap of speculation, there will be no attempt by Sony to block used games being played on the PlayStation 4.
Months of talk and even an unearthed patent led some to think a pre-owned ban was coming, but it seems Sony has sided with the consumer and its retail partners.

Though the PS4 was officially announced tonight, and some details of the product's specifications and features were provided, Sony neglected to mention whether or not the console would let customers play second hand games.
When pressed on the issue by Eurogamer's Tom Bramwell, head of Sony Worldwide Studios Shuhei Yoshida was at first evasive, and possibly stalling for time.
"Do you want us to do that?" he asked.
