I already own one... I'm a little disappointed at how many people answered no on the poll but then again, the community of the Escapist has never been all that Nintendo friendly.
Anyway, The Wonderful 101 is a game I've been looking forward to since it was announced, and was the game I wanted most as a launch title. I was very disappointed to find out that it wouldn't be out by launch and that it may be released quite a bit later for those living in the UK and Europe.
I naturally want Super Smash Bros but I know that's not coming out for a while, I'd assume Christmas time 2014, if we're lucky. It will be nice to see screen shots and a trailer for it at this year's E3... I'm also hoping the start up a Dojo site for it like with Brawl; I loved following each of the updates.
I loved Kirby's Epic Yarn, though I love all things Kirby, and it's nice to see a spiritual successor to it. My little brother's favourite Mario character is Yoshi so I think this will be a good game to get for his Birthday or Christmas. Here's hoping it has a co-op mode.
I was disappointed by Mario 64 and was put off from 3D Mario games, but when I got a small chance with Super Mario Galaxy 2 I found it to be incredible, so depending on how it looks at E3, I might also purchase this new Mario game.
Wind Waker is my favourite Legend of Zelda so there's a purchase or Christmas present addition for me.
There are still some things I'm hoping for, for instance I'd love to see the next BlazBlue game available on the Wii U. I would also like to see some of Nintendo's IP's that haven't been getting much love make an appearance, like a new Star Fox or F-Zero game (heck, surprise me with an all region?s Panel de Pon starring Lip or a console made game of Dillon's Rolling Western). Nowadays though I don't play games quite as much as I used to so hey, maybe this will be enough to satisfy me. The future of the Wii U looks promising.
