With the update Nintendo is releasing next week they have a few new options. One of them is to hold "B" on the Gamepad/ Gamecontroller and it will boot directly in to vWii mode. I think there is a possible way for us to get in to that. (ofc. from the moment that we can look in to the memory from the WiiU.) When we are in that starting sequence I think we can insert our own possible .elf loader. So yeah. It's a big "IF"... but it's possible.
