I'm surprised so many people want to use the d-pad. Was the sideways Wii Remote control scheme really that amazing?
I don't think anyone seriously did, the people who want the D-pad aren't comfortable using the circle pad because it's not "good enough" to control a game like this for them. Even though it would clearly be way more limited in general if they used the D-pad (and I am aware of how it worked on the Wii Remote, doesn't mean it wasn't horrendously limiting).
I'm sure people who want the D-pad will be using the actual analogue stick on the Wii U. It's only a common complaint because of the way the circle pad is designed (aka not really for this game).
