Coming from a Penny-Arcade interview with Emile Pedneault...
“I'm not here to speculate about the status of it right now, but we just delivered the ultimate experience and we just took advantage of all the Wii U features in every possible way we can. So hopefully, things will pick up in the future, and we'll make some new and old fans pretty happy with this version. Who knows, maybe we'll be that one game that makes the Wii U sell.”
I don't think ports of recently released titles will make for system sellers, but I hope I'm wrong!
