Except it is "hardcore" (Like that really means anything at this point) rather with Gamepad or not. Gamepad isn't going to be standalone. Just not going to happen and there's no reason too. At most you get remote play to extend it reach which is probably going to be in the NX portable anyway. Battery, heat and cost. Not going get something actually portable and something like the Wii U or greater in one device.
If the NX is getting a gamepad, they are mostly going to change it, so more people will like it. Like I said, wifi single so it can work like remote play. Cheaper components. Smaller and reduced everything, including battery, but also screen (unfortunately). Probably 5in. Less weight,size, cost and power. Streamline programming for devs even farther. Also, yes, nonstick rubber please. Probably get rid of that thing on the bottom and just use a regular charging port.
