Dont buy a wii u right now abd here are the reasons
1. Most games dont have online multiplayer
2. No impressive games coming up
3. Almost all ps3 games ported to wii u lack online and dlc
4. Highly anticipated games like fifa 14, battlefield,GTA 5 are not coming to wii u
5. If you buy a digital game from eshop you cant transfer it to anthor console( even if you sold or lost you wii u)
Those are the dis advantges but i suggest you buy it if you love mario and zela
