Wow... I've heard some great things about you Gilgamesh, but this was disappointing.
Nintendo have the games that made the DS so successful. The Vita has high priced hardware and software that didn't sell to well on the PSP anyway. And people generally don't want home console experiences on the go, so don't count on games like Call of Duty to push sales too much.
Of course it's still too early to tell, but already saying that 3DS will lose is just foolish.
