The Vita is not a gaming tablet. A gaming tablet's screen wouldn't be anywhere close to as small as the Vita's, that's against the entire point of a tablet and against' the idea that they could "just put both screens on the tablet," so yeah, it would be noticable, especially launching at the tail end of in 2016.

540p on a gaming Tablet would make it look ancient and extremely undesirable, which doesn't matter because there's no way it's even happening. Dual screens are never going away.

Well if Nintendo is going for gaming tablet, probably will go for 720p.

...I'm over here predicting that the NX will be a unified digital only platform with amiibo as the only form of physical media, and you think I'm opposed to change? I'm not opposed to anything. I just think you're wrong and I think it's blatantly obvious that I'm not. I'm not merely basing this on Nintendo historically, but Nintendo of the past 2.5 years and what they've recently been saying and releasing, which flat out contradicts 85% of what you're speculating. You can pin it on me being "opposed to change" all you like, but it's really just me seeing the blatantly obvious.

Nintendo gave the 3DS a 240p screen to cut costs. You seriously think Nintendo would go from that to a 3x larger 720p screen, just to have the number on the box? No. If they were going for a gaming tablet, and they are not, it would be a much lower resolution, because that would be an unessecary waist of money. The NXDS can have a 720p 3D screen because the screen is like 1/3 the size and wouldn't cost nearly as much money.

Then they could just throw in a 420p (or less) screen for the bottom screen and call it a day. The NX console may get a slight boost with a 540p Vita sized screen, trading the larger screensize of the Wii U for the better resolution of the Vita screen. Not cutting edge on either side, but Nintendo never needs to be.

I don think Nintendo will go for gaming tablet.

Like I said, resolution 540p-720p for NX handheld/gamepad (or whatever) screen of 5-6" will be enuf, 720p will be enuf and for 8" display. And I don't see they doing another DS device.

Their only path is to go with another DS device. It's the only thing that fits with the unified platform. Going single screen would absolutely destroy any seemlessnes for a unified platform, since the hardware wouldn't be uniform. For a unified platform to work, the handheld must be as symetrical as possible. That means as many imputs as possible must be shared between the two. That's why the N3DS was made. To be more similar to the Wii U, likely to test this concept without needing an extra periferal.

Two screens, two analog sticks, for face buttons, one dpad, two digital triggers, and two bumpers. The only thing missing is the analog clicks, and that is a less than tertiary input that can still be added to the NXDS in some capacity. For now, though, games like Hyrule Warriors Legends are perfect analogs for what to really expect from the NX and NXDS. What's on the top screen will be on the TV. What's on the bottom screen will be on the gamepad. After that, it just comes down to optimizing the HUD for the smaller screens' real estate. No building an etirely new game because your two peices of hardware are asymetrical.

I don't see any connection between DS device and unifying platform. I dont think we will se DS device again, I think better chances are for Wii U concept, using NX device like Wii U gamepad for playing some games (probably Wii U games) on TV.

3DS and Wii U are not symmetrical platforms at all.

The DS/3DS are really effectively just one vertical screen, seperated by a border that you can quickly look at. The 2DS even took that further and is literally just one screen with an arbitrary plastic border between it.

The Wii U is nothing like that. The screen is completely separate from the TV screen, to look at it, you basically have to stop playing, look down, and then look back up. It's a concept that just doesn't work very well to begin with not surprised a console based on this idea has been a massive failure. 

Even when I play DS backwards compatibility games on Wii U, I usually have the screen mode set so that both screens are on the Wii U tablet and I'd bet that's probably how most people do it. I don't want to have to be looking up, then pause, then down, then back up to the TV. It's much more closer to the DS experience to have the screens side by side on the Wii U tablet screen even if it means they are horizontally side by side.

In any case for backwards compatibility just allow the screen to be held vertically. If you need to add "side wings" or a cradle type thing for physical controls, then so be it. It would just be a piece of plastic that would cost a few pennies to manufacture. 

Not all hardware. It was pretty normal in the 90s to pay $2000 - $3000 for a decent PC, nowadays it's usually $800 - $1200.

Average prices for TVs, monitors, mass storage, RAM, "music players", "movie players", cameras and other entertainment devices have also gone down a lot over the years.

The connection is Nintendo and their history of devices with dual screens. If this was Sony making a unified platform, I've be arguing a single screen, because it would make absolutely no sence for Sony to make a dual screen handheld and console at this point. It makes even less sence with Nintendo to do the opposite, since removing the bottom screen from only the handheld when the console still has two screens would make it incompatible with NX, Wii U, DS, and 3DS games for literally no good reason.

Not going to happen. It's already confirmed that there will be both a handheld and a home console, and it's already confirmed that they will be apart of a unified platfrom. It makes no sense, then to have your console be some weird portable hybrid that plays the console games on the TV that you can then take with you away from the screen. Absolutely no chance anything like that is happening. That completely goes against having a unified platform.

What is event the point of having a unified platform when your console is already portable? Why would Nintendo make a device which is capable of having dual screen play, but limit that to only legacy games? Why would Nintendo make a device that forces developers to make every game playable with only only screen, when they are making a device that can support two? Why would any developer create a dual screen game for a system that would primerily be played with one screen? Why would Nintendo make any device that would make a developer question that? Why would Nintendo, then, be making a dual screen device where most of the games would render the bottom screen useless when plugged into a TV, rendering the botton screen a nuisence since it would negatively effect the urganomics of the controller for no reason? What are Nintendo going to do when all NX games are made to use a single screen touch screen that can't be seemlessly emulated on a dual screen TV set up? Are you going to touch the TV screen? Is every game going to be like Kirby Canvas Curse where the same thing is shown on both screens, but since you need to look at the bottom screen to use any touch functionality, you'll just look at the bottom screen the entire time, making plugging into the TV useless? Why would Nintendo waste money producing such an extremely flawed and useless device at all?

No. They'll make both dual screen, just like with this generation, and they'll both talk to each other seemlessly, unlike this generation.
