It's been a long time coming, but Nintendo will have some news on the app shortly.

The status of the much-delayed Nintendo TVii service in Europe will be announced "in the near future", Nintendo confirmed in a recent update.
The app, which has been inactive on the European Wii U menu since the launch of the system, was originally intended to launch in 2013, prompting Nintendo to apologise for the extended delay on their official website (discovered via Nintendo Life.)
Nintendo TVii was made available in North America and Japan in December 2012. The service connects with television providers and streaming services such as Netflix and Hulu Plus to provide a library of TV content. Users can also utilise the GamePad while watching their program to look up information and reviews about the show, as well as share their thoughts on Miiverse.
Hopefully they delayed to deliver them the beta run of TVii 2.0Something on the Wii U that Loads Quickly and Responds Immediately that is part of the base OS. Yeah. You be dreaming. Nintendo really dropped that ball on that.
an actually useful and fluidly interactive app that loads quickly and responds immediately when you touch something.
Surprisingly, once you are logged on, switching profiles back and forth is really quick.That must be a recent improvement.
I think that's the only positive thing I have to say on the subject at this time though....
