Is it Game Over for Nintendo DS and Sony PSP?

Portable gaming, played primarily on Nintendo DS and Sony PSP devices, has been dominated by these two companies for over two decades. In this model, at retail, consumers pay around $200 for the gaming device and up to $40 for popular game cartridges. Because of the similar form factor, overlap in consumer base (especially younger players on iPod touch) and the casual nature of game content, Flurry combines iOS and Android devices with traditional portable devices to form the category. With the inclusion of smartphone game revenue into the category, shifts taking place in market share become clearer.
