'Nintendo's holding the crown for too long' being your argument for Vita outselling the 3DS is probably the most ridiculous I've seen on this site. The games and the market for those games always decide the success of a console.
Are ANY of those (Final Fantasy, Gran Turismo, Resident Evil, Monster Hunter) games announced? Not one. Funny thing is all those games are released on 3DS and deciding its success in Japan. Also those games keep coming for 3DS. With Monster Hunter 4, a official sequel of Monster Hunter, releasing next year exclusively for 3DS, it's already garanteed Vita will probably NEVER and for certain not next year outsell the 3DS. With what games? There's nothing exciting announced for both western and japanese gamers for 2013.
Call of Duty on Vita being a success? And Fifa will exceeding this? You call 350.000 sold copies with a game averaged 3,5 on Metacritic a success compared with the millions of millions sold on the consoles? Fifa Soccer also didn't managed to sell half a million while consoleversions sell millionS. You can't call that a succes. That's being ignorant.
There is so much BS in your third paragraph, I don't know where to begin... 3D isn't the main selling point of the 3DS, it's the games (Resident Evil, Monster Hunter, Dragon Quest Games, Bravely Default, Project X Zone, Mario, Zelda, Kid Icarus). The 3D is a extra feature like 3D on the PS3 but the 3DS already managed to outsell the PS3 in Japan despite it having 3D? Where's the logic?
When are we done with the 'head aches at little kids' argument? Those were temporarily because of Nintendo-hate. I've never heard of it in months again.
...I've said enough. It is time for you, as a Sony-fanboy, to go on and accept Nintendo will be the handheld-king for many years coming. Because you like sony, doesn't mean you can ignore facts that tell the opposite from what you want to be true.
