It's utter nonsense.
The suggestion that there are about 80-160 million dedicated gamers out there, but Nintendo never sell any of their systems to any of them, is just ludicrous. The PS2 sold just as much to "teh cazualz" as the Wii did. What was different about the Wii was that it also sold to people who wouldn't otherwise have bought a gaming console at all, and sparked an interest in games amongst those people.
Some of those who bought a Wii will be satisfied with it, and won't upgrade. Others, however, will buy a new gaming system at some time in the near future. Why not now? Because there's no rush for these people. They don't need to buy systems on day 1, they aren't buying systems because they're "flashy and new", as the so-called "hardcore gamer" does. They're buying systems because a particular title has captured their interest.
With the Wii, many had their interest captured by Wii Sports. No equivalent title is on the Wii U yet. As such, the Wii U is currently selling to those who would have bought a gaming system anyway, as is the PS4 and XBO. As the Wii demonstrated, it only takes one game to capture the attention of the mainstream, and Nintendo is best-placed to create that game, due to their approach to gaming.
Dedicated gamers make up a very small portion of the install base of video game consoles.
What I also found hilarious was the assertion that, in Gen 6, Sony and MS were, collectively, the main forces, with Nintendo "picking up the table scraps". Never mind that the Xbox sold about the same number of units as the Gamecube did. Apparently, Sony had about 150 million fans as a "stable fan base"... and so, 360+PS3 is that fan base, spread across two consoles. Completely ignoring multiple-console owners, of course.
