So, Nintendo ususally has more or less the same ammount of new IPs for both it's Handhelds and it's Home Consoles, so I think this is something we can all talk about even if we have different ideas on what NX will be, but don't worry, if you have an Idea that has to be made on a specific console share it anyway, good ideas are always appreciated.

I personally think that NX will make Game Development faster at Nintendo so there will be space for both old and new games. In average I'd say that they might make about 10 New IPs them beeing both major titles or little ones. This are some of my ideas:

1- A new JRPG by Monolith (only after the third Xenoblade) in a more Fantastic world;

2- A Next Level Games multiplayer competitive game (not particular gender)

A new Golden Sun!!God, we are deeply missing a new golden sun.

wait you are saying xenoblade chronicles isnt amazing enough? what the hell xD no no, xenoblade chronicles series should continue, its amazing

Couldn't tell ya. A key thing about Ninteno games is that a lot of them are really tied to Nintendo hardware, and their hardware is never vanilla. Which I love because games like Splatoon, Sin & Punishment: Star Succesor, and Super Mario Maker would never really be the games they are today without how thier hardware. We can safely assume at least one new concept IP though

Let's see. How many new IPs has created Nintendo this generation on both platforms?

3DS
-Codename STEAM

WiiU

-NintendoLand (new IP is questionable)
-W101
-Splatoon
-Project Guard? What happened to it, again?

Other

-Pushmo
-NES Remix (new IP is questionable)

I don't know if I have left some there.

I think they'll make a similar number of new IPs. They'll resurrect a couple of old ones too (like they did withKid Icarus and Fire Emblem this gen).

They also did The Wonderful 101 (guess it counts) Boxboy! and many more, still they are minor titles as I said
