Also perhaps they borrowed the devkit from work/ have kids they dont want messing with their devkit?
That's not how Nintendo does things with devkits. They have some very strict prerequisites before they'll even allow you the opportunity to buy a dev kit. You can't just put together the money and buy one like you can do for a license for Unity3D or Unreal Engine. Nintendo wants you to jump through a lot of hoops to even qualify for the right to buy it.
First off, you must have a physical office, and not be just working from home. So that rules out the kids thing.
The office must have a room that has no windows. The room with no windows must be locked with some form of electronic lock that identifies who comes and goes. The dev kit is NOT to leave the room. An individual game developer (person, not company) is only allowed so much hands on time with the dev kit and they must log exactly what they do with the dev kit during their time with it. What's more, if this actually works, they'd have been demonstrating it on a regular WiiU, as that's the system the hack would be being tested on in the first place. This entirely rules out borrowing a dev kit from work.
I'm sorry, but as much as I WANT this to be true, the fact that it's a dev kit means that it's capable of running unsigned code and having channels installed to it without the use of an exploit. That alone makes it extremely suspect and CANNOT serve as evidence that this is real.
Saying "Bubba and Harry said it's real so it's real" is an appeal to false authority fallacy. I don't know if this is true about Harry, but Bubba doesn't seem to have access to the hack itself, but rather is relaying information. This means that he is not an authority, as he knows only what he's been told. As for Harry, he's the guy who posted the video, but I don't know if he's the guy who recorded it. If he was given the video, it makes him a false authority, if he made it he's an authority. In the case that Harry is an authority, not a false authority, due to the contamination of the evidence by the fact that it showed a devkit running the channel, we have only his word to take for it.
Again, the very fact that the only direct evidence we have is the thing running on a system which by default is capable of having unsigned, unauthorized channels installed to it without any special magic, I'm very very skeptical and writing this off as yet another hoax (like with the Fail0verload troll face thing). I hope it is real, but I really really doubt it.
I am however hopeful that something will come of the c0c3 talks.
It's kinda funny going back and forth between this thread and the "WiiU and WiiU gamepad hack.." thread. There is just too much anger on the subject. I guess people need there hacking fix.
Piracy is not one of my concerns. I only care about being able to make stuff for the WiiU without having to jump through the above hoops. The WiiU is an amazing piece of hardware, and I'm especially thrilled about developing things using the gamepad. Honestly, I would settle for simply hooking the WiiU Gamepad up to my PC and using it as a monitor, touchscreen, and gamepad. That ALONE is enough for me. I don't even need homebrew on the WiiU to do that.
