This seems like sony. They made PSP to have their Games be made portable to compete with Nintendo's Portable, while being able to play music like an iPod. Now that Nintendo will be launching 3D Games, and Apple has made iPhone along with Microsoft who has now made a Window's Phone, its no suprise Sony will try compete with everyone they're against.
