GameGuru writes-"Two agents of destruction (Ryu and Snake) seeking for retribution, set out in their quest to meet their destiny and conquer their fears in the month of June, but it seems Snake’s saga is going to chip Ryu’s “gaiden” (Japanese for the continuing saga) into a million pieces even prior to its release
Sony did something similar with Heavenly Sword releasing it on September 12, two weeks before Halo 3 and although it was a new IP with excellent production values, it did not quite make the grade that it was expected to initially (in terms of sales). It took the game a considerable amount of time to hit a million copies. Had Sony delayed the game till October it would have fared much better in the absence of Grand Theft Auto 4 which was due to be released in 2007 at that point of time."
