I have a hard time believing that it's Lightning Returns, given that that game uses a proprietary SE engine that likely hasn't previously had any English documentation. Is there evidence that this port is still in development? IIRC, Straight Right said it would be announced "soon" several months ago, so it's not inconceivable that it could have been cancelled based on poor sales of other third-party titles on the platform.
I was kind of wondering if it actually was Hitman since I don't remember them every announcing that wasn't coming to Wii U like they did with Tomb Raider, but then they canned it since they can projects fairly regularly at Square Enix these days.
