I'd love to shit on the Wii-U some more, but this is some epic nitpicking. The fact that Yakuza 1+2 are coming to the Wii-U should be enough. As long as it looks nice (it does), and it plays well (wait and see) - there shouldn't be a huge issue.
People with a PS3, grab it on that. Wii-U only? Well, now you get to play…
