I know people aren't really going to know yet, and someone from the community is going to need to risk their £250 Wii U as a Guinea Pig, but we need to figure out what will happen. I never pirated games or anything, I just used Gecko, Savegame extractor and a couple of emulators, but surely if we can't pick and choose what it transfers, it will attempt to move over the Homebrew channel, which could brick the Wii U. Honestly I'm concerned that even having the HBC in play history will raise alarms. He's what I'm planning for mine: NAND backup the Wii. Find an app to erase all traces of play history. Erase HBC as thoroughly as possible. Attempt Wii U transfer. Restore Wii NAND? Any other precautionary steps?
