The rumor/announcement comes from sources of the Wall Street Journal “familiar” with the plans of Sony regarding the PlayStation 4. The report claims that the streaming of current PS3 games will coexist with games on optical media sold through traditional means.
This rumor seems plausible since Sony acquired the streaming company Gaikai last year for the tidy sum of $380 million.
It’s expected that Sony will officially make an announcement on the subject during their event on the 20th.
