I am absolutely down if it means a shape that actually allows you to use the controls and the front and the shoulder buttons without some sort of bizarre balancing trick. My main problem with the 3DS right now is that it requires either using your forefingers to hold it up, making it hard to press the shoulder buttons, or you have to really grip it with the base of your thumb, making the face controls awkward.
If this solves that issue, I am so ridiculously on board.
Also, this really doesn't look to make it too much bigger or really strange looking, so I don't really see a big issue there. And I doubt it's going to be used for every game anyway - a lot of 3DS games and series have no real need for it. On top of that, I know virtually no one who actually cares about how portable the 3DS is, most keep them at home and those that do ever take them anywhere just throw them into a bag anyway (I would never want to carry a 3DS in my pocket).
Gigantic lol at all of the people talking about how this is a blatant money grab to make up for the price cut. Right, because it's completely unreasonable to expect you to PAY for a peripheral. And the fact that they released a peripheral clearly shows that Nintendo is a failing company.
...and then people compared it to the Virtual Boy. Seriously? My guess: people making these comparisons weren't actually alive for the Virtual Boy. You don't even begin to comprehend the amount of fail involved in the Virtual Boy. The success of the 3DS is already orders of magnitude beyond the Virtual Boy.
And how on earth does this "screw early adopters"? I don't see anything about how this is free for late adopters or somehow costs more for early adopters?
You guys will find a way to complain about anything.
