That 4 button placement looks awkward. I'd have to reach across with my thumb towards the center and that might get unconfortable after a while. Once again, just like with the GameCube and Wii controllers, not good for fighters.
The problem is that, if they swap the 2nd analog with the 4 buttons, it'd just be a 360 controller.
1. Star Fox Wii U. Must be free-roaming, i.e. not rails based. MUST be online, and ideally play kinda like Diablo 3 does. Go through story mode and level up your fleet and weapons as you go, friends can join you with their fleet if they wish. Must contain multiple star systems with plenty of levels each and many characters to choose from. If they do this, the game will sell like hotcakes.
2. F-Zero Wii U. Track Editor REQUIRED. Port the one from the 64DD expansion if you have to. Upgrade the vehicle builder, and must be online. A way to trade built vehicles/tracks with be a nice addition too.
3. Smash Bros 4. Online has to be more seamless, include more characters (including Megaman) but also do more QA Testing for this one...Metaknight was way overpowered in Brawl. Take out random tripping.
4. Super Mario Wii U. The next 3D Mario installment. Put a slightly better story to it with some more dialogue. Visitng actual "planets" would be nice.
5. The Legend of Zelda Wii U. Make the real time play just like the trailer back in E3 2011.
6. Pokemon MMO. This would be awesome. Battle your friends Pokemon online/compete in stadiums.
7. Super Wario Bros. It's going to happen someday.
8. Super Koopa Bros. The exact reverse of the Mario Bros. You take control of Bowser or maybe one of the Koopalings and take over the Mushroom Kingdom. Enemies have to be Toads, final boss is Mario before you get the princess.
