Cheap price and lots of games

EDIT: and what Rol said.

1080p screen. If my phone has it now, my gaming handheld should have it then. Two sticks, multitouch, robust OS and decent internal storage.

Well first off improve EVERY internet feature, especially 3G internet browser that doesn't suck. A virtual console for Atari and Sega consoles or maybe just a more diverse virtual console all together. Bigger console maybe bigger screens with better resolution. It would be cool to try a new control stick not a circle pad. Nintendo could figure out their own gimmick I don't got a good idea.

Dual analog and no region lock please.

Taken from Rol (since it's a quite complete description) and modified :P
1. Bigger d-pad and face buttons. check.
2. d-pad in the primary spot. check.
3. No dual analog. check
4. Mainstream design, similar fo the original PSP's, with a single 4 to 5 inch capacitive multitouch screen. Buttons: d-pad, 1 smaller analog slider, ABXY, buttons, LR triggers, start, select and home buttons
5. XL version available at launch as well. check; 5 to 6 inch screen
6. Stereoscopic 3D is dropped, or made optional in a "3D" version.
7. For the name I'd like the return of the "Gameboy" brand.
8. A substantial increase in processing power, something like Tegra K1 or even Erista depending on price (or a Snapdragon equivalent), 720p resolution.
9. Battery life 8 to 12 hours - price 199$ for the initial version, XL version 239$. One game in bundle from the beginning.
10. Virtual console and account system at the point where they have to be. check
11.) Remote play on TV, aps for internet browsing, youtube, video and music playback.

I think people are either too unimaginative or just wanting more of the same thing - which is the wrong way to go!

What Nintendo needs to do with their next handheld is something NEW, something we haven't seen before. Multi touch and dual screens and dual analog sticks aren't enough.

If handheld consoles are to survive, they need to evolve. They need to offer something smartphones CAN'T, and before this is accomplished all your wishes are moot.

Maybe it'll be haptic touch screens, maybe it'll be some sort of hologram, or whatever. It needs to offer something new. But except for that, I think most thing's have already been mentioned, and launch with GAMES! A console needs GAMES!

Im ok with a better resolution 3DS, even without 3D. 480p for each screen is ok. and a good price.

But seems that all nintendo consoles NEED a inovation.

So, i imagine 2 possibilities:
1- a total integration of the home and handheld systems(and ok, is not so much inovation)
2- tecnology in foldable screens. A single screen with foldable in the middle, that can be turned to a 2 screen scheme.

I think Nintendo should bring out a ipad type tablet device that streams to the TV that you can also sync controllers to, and can play on and off screen like the WiiU now with the options of touch screen or standard controller, bet it would sell like hot cakes in Japan.

I'd like everything in the OP except the specs. For the specs, I'd like an HD handheld, on par with the gen 7 HD twins or even the Wii U. They might be able to manage that by 2018. I'd call the hybrid system the Nintendo Fusion, as per the rumors. Maybe call the handheld portion the HDS. Sell the console, which would be at least twice as strong as PS4, with the handheld for $400-500. Again, would have to wait for 2018 for a price like that to be something they could manufacture without a horrific loss.

Also if you're gonna have SD cards, make them bigger. This 2G-4G bullshit needs to stop. Include a 32G with the handheld at least, and a TB of storage in the console.

As for a launch game, if Zelda U comes 2015, Zelda Fusion could be made by 2018. Maybe a Metroid game too. Hehe, Metroid Fusion...

The 3DS is fundamentaly flawed because they DIDN'T have that thinking: it's too much like the og DS without really adding anything new. The 3D didn't give you a new experience; it didn't really add something to the gameplay mechanics. Don't get me wrong; I love my 3DS - it's the first handheld system I've ever owned - and I think it has far better games that the og DS, but what did it really add? An analog stick and 3D. That's not revolutionizing. The DS did touch screen right and added a second screen. THAT'S how you design something new!

You are kind of contradicting yourself, Rol; "Let's not overcomplicate things. Smartphones don't have buttons [...] what a dedicated gaming handheld has to do is not add things, but remove everything that it doesn't need." Don't you see that those two things are the same? Don't overcomplicate; remove ALL buttons. Handhelds don't need to add, but subtract - and what do you get then? A smartphone. A touchscreen and nothing else.That's all you need really to game in this day and age. Smartphones are as simple and "pure" as it gets.

What you forget is by adding you improve. analogstick: added. D-pad: added. Motion control: added. Dual screen: added. Touch screen: added. If you remove SOMETHING you need to ADD something else. That's how it goes. What people have wished for in this thread is a HD DS with two analog sticks. That's hardly any different from the handhelds we have today, and you think that will sell more than current handheld systems? No, it won't.

And we're seeing that Mario, Zelda and Pokémon isn't enough to really push handhelds any longer. 3DS will never sell past 100m, 80m seems far more likely. It probably will just pass the 50m mark this year, maybe 55m - tops. And that's all fine and dandy. 80m isn't a bad number. But what about next gen? If all we/the market get is yet another DS system without anything EXTRA added, we'll see further decline in the numbers.

I do agree with you fundamentally though; Nintendo needs something simple, something easy, something cheap. But they also need something new, something that can't be found anywhere else, something novel, or next gen will be the last handheld gen.
