They should have ended with Pikmin 3 if that was all they were going to show. Pikmin looks gorgeous, but Nintendo really needed more. I'm wondering if these games are just the titles that will be at launch window and they will announce more later, because it's really disappointing if that's all they have prepared for the system.
The Wii got a Zelda port, a gorgeous 3D Mario, Metroid Prime 3, Red Steel, and arguably excite trucks for the "hardcore"at E3 2006.
Wii U gets Pikmin 3, Zombi U, and arguably Super Mario U for the "hardcore."
With that said, I will probably buy if they are good:
1. Pikmin 3
2. New Super Mario Bros U
3. Rayman Legends
4. Lego City Stories
5. Zombi U
6. Nintendoland
So, yes... I am personally happy, but it was very underwhelming.
