so guys, im from the future. here to give you some details on the 'nx'.
first off, the leak is real, but that's not the final product. although the final product is very similar, it is slightly larger and feels more pleasing to hold, even on its own. what you could compare it to is like a cross between holding a wiimote, and holding a phone (horizontally, of course). i'd say it's more comfortable than the wii u gamepad, but that's my opinion - some prefer the gamepad, but that really doesn't matter for reasons i'm about to get into.
now let me just say, i'm with you if you think it's not a good design for a controller how it is and how you see it right now, but as for the final design, you will change your mind... why? when you purchase the "NX", it comes with the console, core gamepad, hdmi and cables, 2 games (one of them is basically just for showing off the features of the "NX" itself), and the classic controller attachment.
now you'll probably be excited to find out that the core gamepad's design is how it is for a reason. while it is perfectly fine to use how it is, it's also designed for attachments. the attachment is comes with, the classic controller att., is exactly what you'd expect, it has those hand grips and is incredibly comfortable. in case you're worried about it being too bulky, it's not. also, the way the attachments click in is super satisfying, like more satisfying than the sound of putting in cartridges into the NES.
so there are a few other attachments, a couple of them are just for the feel, but others have special functions. There is one attachment i'm not going to mention, but i'll give you a hint: it is something that has been called expensive and gimmicky in the past. (btw, that's not to say it is in this case, nintendo pulled it off pretty well)
as for the other attachments, they're all pretty awesome. there's this other one that adds a totally new set of controls, so if you really love physical buttons and shit, that'll be for you.
speaking of buttons, the way they are set up on the core gamepad is really intuitive, i wont go into it much, but i will say that after using it, you wont care much about physical buttons. the haptic feedback really does its part. as for the shoulder buttons/scroll wheels, they feel so satisfying to use... this is a very satisfying controller in general. oh also, the circle pads have haptic feedback as well.
im too lazy to write anymore here, i'll answer just one question, and 3 yes or no questions. edit: nevermind, i broke my own rules.
