Considering Wii U hacking is still in its infancy, it would be ridiculously preemptive to separate the sections now. Maybe once the Wii U is hacked and there is legit homebrew development happening for the Wii U side of things, then a separation of sections may be in order. As of now, there would basically be one thread left in the Wii U hacking section, and everything else would be offloaded to the vWii hacking section.
