I'm not at that point yet, if only because I no longer have a Wii and there are too many times I load up mario or Zelda on virtual console to play for a quick few minutes. Not only that, but I have a handful of games on my backlog for Wii U i'd still like to get through (Twilight Princess & Wind Waker HD, Xenoblade Chronicles and X).
That said, I have to admit entertainment center real estate is becoming a much more real problem than I anticipated, and having 5-6 consoles set-up on a tv creates a real cord problem. I might migrate my Wii U to a TV in the bedroom once I get through the more visually impressive games on my nice TV as a way to lay in bed and play virtual console or simpler games, but I don't have guests over often enough to justify a spot on the main tv for multiplayer games lately.
It's too bad, I really do like the Wii U, and it's always been a way to get some color and unique gaming experiences, but like you, i find the time actually spent on the console lately is limited to my alternatives (PS4/PC).
