I'm not contented with just Mario... But the 3D ones are among my favourites of all time. So, a new title of that kind is enough reason for me to purchase the console on day one. I'm sure there will be other games I like.

I'm afraid i got a weak spot for Xenoblade. It's what made me take the plunge with the Wii U.

So... new Xenoblade and a couple of more that interest me. Not buying at launch though. Nothing can change that.

Regular box, with a regular controller, less than $200 and I´d buy to play a couple nintendo games I care.
Not buying the gamepad hybrid thing.

Hoping a price for $150

Breath of the Wild on the go :o
Although I feel like I'll be excited about a lot more than that as well, I'm just waiting to see what happens!

I've been slowly warming up to it. The ability to play Gamecube games anywhere was enticing enough (hope Killer7 comes down the line), and the promise of third-party games (not making much hopes up since that's what they said for WiiU too, so time will tell) is always nice.

Regardless of price, I won't be getting it when it releases, but I'd hope to get it somewhere down the line. Something that would sold me on it Day One would be a confirmed Ace Attorney game on it somewhere near launch. Something that's pushing me already to the idea of getting it sooner than later is the rumour of the Souls trilogy coming to it.

Considering how much of a disappointing let-down the WiiU is in my eyes (and to an extent, 3DS), it is kind of amazing that Nintendo has managed to come up with something that I'm liking toying with the idea of purchasing it.

the brand

i wished it had more sales.... to secure a new xenoblade game....

that game is perfect if it wasn't for the fact that they were suppose to be a few finest people from earth and most people there are so fucked up :P

Dark Souls and Trophy/Achievement support.

Decent price, responsive OS that has decent features liking sharing/screenshots/maybe achievements, fairly strong launch lineup. That's to convince me to get one at launch, I'm already pretty convinced on getting one eventually.
