Nintendo never "disrupted" anything. They created a new market, and they have it practically all to themselves. If they had disrupted something, we'd see traditional gamers flocking to the Wii in droves.. but we don't.
You can't truly claim that HD console adoption hasn't reached previous console levels by itself, due to "Nintendo disruption". There are a LOT of other factors in play -- namely that the PS2 still is in production, that HDTV adoption was slow, that Blu-Ray adoption was slow, that there's an economic crisis... on and on. Those factors are significant. Pretending its all Nintendo's doing is folly.
