Just found two interesting quotes via Kotaku
"We needed to make sure that there was really an opportunity for it. We wanted to see how it would sell in Europe, and based on the performance in Europe, we would look to bring it here to the U.S. It did well in Europe; we decided to bring it in here. We took a very smart approach and we sold it ourselves online in terms of physical goods as well as a focus on GameStop as a retailer, and it was a very good effort for us. (It sold) Quite well."
On Monolith's Wii U game:
"We know that they're working on a game. I personally haven't seen it, but I know there's a lot of excitement in Japan and Kyoto about what they're working on, so I look forward to seeing it. In the end, if it's a game that we decide to publish from... what would be a second-party standpoint, certainly we'd love to bring it here to the US. The way we look at the opportunity is, given a level of marketing support, how much are we gonna sell and is it gonna be a profitable venture?"
