The chances of getting purely dedicated servers on the Wii U is slim. More likely it will have hybrid dedicated servers that will have a P2P interface. Why not have the feature to use a Wii U console to run a dedicated server machine at home? Something that you can put a server name on it, auto messages, as well as punt/ban gamers like PROCON on PC. I'm planning to get another Wii U so it would be nice to have this feature. I will be able to run a dedicated server on another Wii U & play on the other.
Hopefully A_Trey_U will read this & pass this along to Treyarch Team.
