You think that the homebrew people are the only people that can do anything? Do you think they are the best in the world at what they do because they introduced you to the world of hacking? If you think that they are the only reason the wii online games were hacked, you're mistaken. Sorry, wii hackers are like puppies.
Which might make what he's saying true. Not a whole lot of people are interested in hacking the Wii U, I'd wager. And if the team that spearheaded most of the hacking on the Wii has no plans to do so for the Wii U, you probably won't see as many hackers. If most hackers were really only script kiddies on the Wii, it's entirely possible you won't see hackers on the Wii U, though I doubt that.
Good argument.
