Well ... I was on Youtube on my 3DS yesterday, and I was thinking in myself, dat 480p :S

So, if Nintendo would release a HD DS in the next few years (2015-2016) would you buy it or would you stick with your 3DS? 

I would definatly buy it. It would be awesome to play handhelds in HD + ability to play 3DS games on it. 

How about you?

I'm willing to wait until the next proper handheld generation.

DS: 2004 release
3DS: 2011 release
HDS: 2017-2018 release at EARLIEST

They have the highest selling gaming platform. There is no hurry to release a new model/the next handheld until the 3ds starts to burn out. I would think with the way technology moves that it'd be released sooner, but with 3ds' flying off shelves there is no reason to.

not yet, i just upgraded to the xl this past august... Maybe like 2016/17

      I think we should wait until 2017-2018.

It wouldn't make sense to release an update with HD as all games play in SD. the next console will probably be in HD and that I am willing to buy since it is a new console with new games

I think the next Nintendo portable will be a new third pillar product line.

Something more akin to a Nintendo tablet which has the horsepower to even approximate Wii U engines/ports at lower resolution/assets if Nintendo wants to dual release some games.

By late 2015 this should be comfortably possible for Nintendo at an affordable price.

I say that too because it seems like the 3DS seems to have had its peak year in Japan hardware wise, even with MH4/Pokemon sales are going be more than 500k short of last year there. In NA/Europe this fall is probably the 3DS peak. So I don't think Nintendo will just accept lower 3DS sales every year from here on out.

Announced in 2016 I think.

I don't want a redesign of the 3DS in HD, cause most games won't be able to take advantage of it anyway. Next handheld gen I think it NEEDS to be in HD. The year of 2017 ppl are bringing up seems about right. Would'nt make a fuss if it was in 2016, but 2015 is to soon.

I don't think the 3DS will be "replaced" any time soon, but honestly they've "spent" most of their big franchises on it already anyway. It can coexist with a third pillar Nintendo portable device because it should be $99.99 by then, so it's going to be stocked for years to come anyway. 

NSMB, 3D Mario, Pokemon, Smash Bros., Mario Kart, Pilotwings, Kid Icarus, Animal Crossing, Yoshi, Tamadochi Collection, Brain Training, Nintendogs, Zelda, Luigi's Mansion, will all have already been released for it by the end of 2014. I don't know how much they'll even have in the tank for software support for 2015/16. I wouldn't be surprised to see New Super Mario Bros. 3 next year too ... even next year, the lineup seems like it could be a lot thinner.

They probably will want a new third pillar sooner than later, because they're probably not going to get the profits they want out of the Wii U. Late 2015 isn't that early to be honest, the 3DS will be almost 5 years old by then and it's probably not going to sell anywhere close to the DS, so it doesn't warrant a life cycle as long.

Also I think with the growing threat of tablets/phones getting into the hands of more and more kids at a younger age, Nintendo simply is going to have to respond with something new or accept decelerating sales in the handheld business year by year. I think 3DS has peaked already (probably actually peaked last year in Japan) in terms of sales, it will have lower sales in 2014, and probably even lower in 2015.
