Last week French gaming site, PS3 GEN, claimed that a Sony release timetable had been leaked. The timetable listed Uncharted 2: Among Thieves for a release on September 30th this year. Gamingindians.com/ were told the same thing from an undisclosed ‘extremely reliable’ source. With Uncharted possibly scheduled for September, it won’t be long until some sort of demo is released. Keep in mind that this is pure speculation and the information here is subject to change at anytime. [Updated - Ed]
