3DS of course, by a large margin.

Most of the Zelda fans already own a 3DS, I bet there will be more Ps4 sold then 3DS's, and Zelda might be maybe up to 400 000. Remember that Nintendo fanbase buys everything nintendo, and nintendo cater only to their fanbase. The order will do great as a new IP

I think the PS4 will win. As another user above me said most Zelda fans (who want to play a zelda game on a handheld) already have a 3DS. I'm thinking 350,000 for PS4, and 320,000 for 3DS.

U seem to be forgetting about New 3DS, which likely won't bring in a ton of new users but a good amount of people who purchased the original 3DS/XL back in 2011/2012 could be ready to upgrade to a newer model.

 handheld upgrades like DS, 3DS, 3DSL, 2DS and now 3DSXL? I guess people have been buying the same over and over again, but if there is no big change in the new 3DS that it can be considered the *Next-gen Handhels* I don't think people would rebuy a new Handheld just to play Zelda. the 3DS have sold porely compared to the DS, and that is because people just don't chose to jump over to a new handheld with small changes compared to the previous model. If these small upgrades becomes an trend over on Nintendo's side,  it will eventually be the death to handhelds, cuz it's money milking to add a few gimmicky upgrades and a bigger screen just to boost the sales. what if Nintendo comes out with a *next gen handheld next year? Cause All the DS handhelds so far, is pretty much the same. just a new prce and a extra new parts to make it appealing

It's been a trend for 14 years now.

Nintendo has released a handheld revision almost every year for the last 14 years which have sold nearly 300 million in that timeframe. It's not killing Nintendo handhelds in any way, shape or form.

Could go either way, but I'll go with PS4 barely.

Annualized revisions of handhelds.

Annualized games such as pokemon. 

Annualized franchises.

Soon we probably get annualized revisions of Consoles as well. 

Probably New set of amibos every year as well. 

And i bet you all are praising and kissing it. 

Loving incomplete games. 

What about these pokemon games? 

Each new pokemon game, is the same game, but got two different editions. and you need both versions to get all the pokemons. i never thought about that until now. Same game, but if you wanna collect them all, you need both versions. WOW. 

If people can't see that Nintendo got the worst ( clever way to milk folls ) tricks in the world to sell products, just let them waste those shitty $$$.

Nintendo wouldn't have needed to release 2-3 different version of the same pokemon game, if people complained about it and refused to buy them, but that will never happen. people will shut up, take up their wallets, give everything they have to nintendo, for buying the same games, over and over with slightly better graphics each gen, or each year. Even two .

They even buy 5-6 versions of the same damn handheld. Next Gen of nintendo handheld, i rather wait 7 years before i buy something from them, cause they will probably save the best for last, to drag those sales the longest

Tell me: where did Nintendo touch you?

Touch me? what the fuck are you talking about?  

so you are supporting 5-10 revisions of the same damn handheld every generation? 

Same old pokemon game over and over again, where you need both versions to be able to catch all those pokemon.

Every new Mario game, even though all those different mario games are well up around 7-8 sequals now. 

Expensive Amibo figures ( expensive DLC's.  Be my guest. It's not my money.

It's an endless circle of the same games,  No change, No new plot. nothing new. 
Nintendo have landed on a gold mine, where they can be as lazy as they wanna be. Lucky bastards
