So, that does look interesting, but no indication if you can add your own video sources to that list. I could watch Netflix/Hulu on my TV already through several sources, I could watch it on my PC, I could watch it on my phone. Having this on the Wii U gives us nothing we don't already have.
The Tivo integration is cool on the surface. If you have a Tivo, though, you already have all of those features in the Tivo. Maybe this could be used to add another client to your Tivo. Odds are, though, if you laid out the cash for a Tivo you have it on the same primary TV that you'll want the Wii U on. And the fact that DirecTV always cripples their integrated Tivos means this probably won't work fully with DirecTivos.
That sports stuff looks interesting but we can do that now with any tablet. Watch the game live and load something like ESPN Gametracker on a tablet and you get the same thing. It also flies in the face of the DVR sports watcher because there is no way this thing is going to support streaming of that data in sync with the playback of a recorded game. Most dedicated football guys I know use a DVR in some way. DirecTV has a ton of "extra data" features with Sunday Ticket but everybody I know with Sunday Ticket is bouncing between games with a DVR so the extra features don't work.
It feels like another box with a million TV options but most of them will never get used in a typical household. Why would I want to use the Wii to watch ABC rather than the normal cable box? What did the Wii add there other than a portal pass through?
