I bought Black Ops 2 for Wii U on launch date and believe me, NOBODY on Wii U is "all talk" because nobody has a headset.
But yeah, it's sad. Nintendo owners beg for the big games and when developers give it to us, we (well, not me) don't buy. I was actually pretty shocked to see how Resident Evil Revelations sold on 3DS. Great game with full features on a console with a great install base. Superb graphics and fantastic reviews and....well, you get the idea.
