Dedicated handheld gaming systems like the Nintendo 3DS and Sony's PlayStation Vita will trigger a "rebound year" that fends off iOS and Android, IDC estimated on Tuesday. A wave of revenue stemming both from the new hardware and from game sales attached to it was expected to last through 2012 and 2013. While Nintendo and Sony might still sell fewer units and fewer games, the frequent $30 to $40 prices of their games would trump the dependence on cheap or free titles on smartphones and tablets.
