I would say next year is starting to look great with 4 big games on Wii U. We got a new ZELDA, FireEmblemXShinMegamiTensei, StarFox and Pokken Fighter. I'm sure there will be a couple more that Nintendo will reveal soon. Like maybe Pikmin 4.
It says you can only claim a downloadcode after april 23. So I assume all games u purchased before are valid. I also got my 3DSXL last thursday :)
Those girls from DeNa got my vote!
