The reason you don't see ads like this against the Wii is that most gamers have grown up. What came off to us as edgy and rebellious when we were young now comes off as immature and a little creepy now that we're older and (mostly) wiser. It always came off that way to the grown-ups, of course, so nothing changes for those who never got into gaming, but attack ads like that would alienate the people who buy games for the main markets.
This leaves an environment mostly free of the childish bickering that marked the Genesis-versus-NES wars (and to a lesser extent the Genesis-versus-SNES wars as well). But since it's really the only thing Nintendo can be attacked on with any semblance of validity, in its absence Nintendo thrives.
Complexity is not depth. Machismo is not maturity. Obsession is not dedication. Tedium is not challenge. Support gaming: support the Wii.

There is much to hate about modern gaming. That is why I support the Wii.
