To be priced at 200$/€.
To work as a controller for the next home console (then i could buy a SKU with just the console for another 200!).
To have big screens right from the start.
Internal memory of 32/64GB so when i buy a game for the home console, i can download the handheld equivalent to the console.

I didn't want to buy a DS. I did. I didn't want to buy a 3DS. I did. I think I don't care what they are doing next. I won't like it but finally I will buy it.

Launch it with Mario Kart and Pokémon

$$$$$$$$$$$$$$$$$$$$$$

Everything the 3DS has and:

-Much better resolution. 720p if possible.
-Full compatibility with all types of SD cards.
-More power overall.
-Ability to use as a controller for the home console.
-Two analog sticks.
-Thinner.
-Not out until 2017 the earliest.
-Better sound.

I want it to do something original, that will make the games feel new. I can't yet tell what that would be.

Games! Many damn games! The games have to be good though, because the "thing" below can be considered a game, too!

Dual analogs is a must, and I'd really like for them to add the ability to call people... Now hold on before you get mad at me, but what i mean it's first and foremost a gaming console, but it just happens to have the ability to call people, that's what I would do.

Why on earth would you not want dual analog sticks?

I never said that, I forgot to include that in my listis all.

Dual analogs are a must for the "4DS".

This.

And WOW! i didn't know the gba was only out for 3 years before the DS took its place. for a system with so many classic games, I'm surprised by that. Mean while DS to 3ds was a 7 year gap!!!!!!!
