When do you think the Wii U's successor will release?

[ROBOTECHHEAVEN]

I think it all depends on where the system is at after this holiday, if the wiiu is not over 14 million by years end. I think they will show off some things for the new system at e3 next year , with a release holiday 2017. I think a launch in 2018 would be bad for them, unless they have a system on par or close to the next playstation and xbox systems and of course launch with super mario galaxy 3 or sequel to mario 64.
